A natural polyphenolic compound was used to assemble nanocomposites. Owing to its stable bioactive properties, bamboo has earned significant attention in material science. Its high nutrient content and hydrophilicity makes bamboo more vulnerable to mold attacks and shortened shelf lives. To produce efficient, multipurpose, long-life bamboo products, a novel technique involving an immersion dry hydrothermal process was applied to impregnate the bamboo with polyphenol-assisted silver-reduced graphene oxide nanosheets. Curcumin (Cur), a natural polyphenol found in the rhizome of Curcuma longa, was used in the preparation of curcumin-enhanced silver-reduced graphene oxide nanosheets (Cur-AgrGONSs). The nanocomposites and nanocomposite-impregnated bamboo materials were examined by field emission scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy. At the same time, a phytopathogen was isolated from infected bamboo products and identified by internal transcribed spacer (ITS) sequences. The nanocomposites effectively inhibited the growth of the isolated fungus. The mold resistance and moisture content of both the treated and untreated bamboo timbers were also examined to determine the efficiency of the prepared nanocomposite. The antifungal activity and hydrophobicity of the bamboo materials were significantly enhanced after the incorporation of curcumin-enriched silver-loaded reduced graphene oxide nanosheets (B@Cur-AgrGONSs). This research outcome confirms that the nanocomposite is a well-organized antimicrobial material for different advanced domains.

The design of new materials with antimicrobial properties has emerged in response to the need for preventing and controlling the growth of pathogenic microorganisms without the use of antibiotics. In this study, partially reduced graphene oxide decorated with silver nanoparticles (GO–AgNPs) was incorporated as a reinforcing filler with antibacterial properties to poly(vinyl alcohol) (PVA) for preparation of poly(vinyl alcohol)/graphene oxide-silver nanoparticles nanocomposites (PVA/GO–AgNPs). AgNPs, spherical in shape and with an average size of 3.1 nm, were uniformly anchored on the partially reduced GO surface. PVA/GO–AgNPs nanocomposites showed exfoliated structures with improved thermal stability, tensile properties and water resistance compared to neat PVA. The glass transition and crystallization temperatures of the polymer matrix increased with the incorporation of the hybrid. The nanocomposites displayed antibacterial activity against Staphylococcus aureus and Escherichia coli in a filler content- and time-dependent manner. S. aureus showed higher susceptibility to PVA/GO–AgNPs films than E. coli. Inhibitory activity was higher when bacterial cells were in contact with nanocomposite films than when in contact with leachates coming out of the films. GO–AgNPs based PVA nanocomposites could find application as wound dressings for wound healing and infection prevention.

The effect of silver nanoparticles on the optoelectronic and photoelectric properties of a nanocomposite material based on graphene oxide (GO) and TiO2 was studied. The data of electron microscopy and Raman spectroscopy have shown that, the formation of a TiO2-GO nanocomposite material occurs during hydrothermal synthesis. The absorption spectrum of the nanocomposite is shifted to the long-wavelength region relative to the absorption of TiO2. The current–voltage characteristics of photodetector based on TiO2-GO nanocomposite films were increased by 2 and 7.5 times relative to pure titanium dioxide without and with the addition of Ag nanoparticles, respectively. The optoelectronic parameters of the devices were also increased, which is associated with growth in the mobility of charge carriers in nanocomposite films.

The paper presents the results of a study of the photocatalytic activity of films formed by titanium dioxide nanorods doped with silver nanoparticles and reduced graphene oxide. The obtained nanocomposite materials were studied by optical spectroscopy, scanning electron microscopy, X-ray diffractometry, and Raman spectroscopy. The photocatalytic activity of the samples was evaluated by generating a photocurrent when the surface was illuminated by a modulated light source of a xenon lamp. In addition, the photocatalytic activity of the samples was evaluated by the degradation of the methylene blue dye, which is a model. It was found that the introduction of silver nanoparticles and reduced graphene oxide into the pores of films made of titanium dioxide nanorods leads to an increase in the spectral sensitivity of the sample in the region of 400-500 nm. The increased sensitivity of the sample to visible light leads to an increase in photocurrent generation and is 2.3 times higher than that of the original sample. Degradation of the methylene blue dye after 100 minutes of irradiation in the presence of a TiO2/Ag/rGO sample was 19 %. This is 3 times higher than in TiO2 nanorods films and 2.3 times higher than TiO2/Ag films. The results of the conducted studies have shown that the improvement of photocatalytic activity is associated with a decrease in film resistance, an expansion of spectral sensitivity and an increase in the surface area of the nanorods.

A highly sensitive and selective Raman sensor has been developed by combining molecularly imprinted cavities, silver nanoparticles, and graphene oxide into a hybrid organic-inorganic film. The molecular imprinted nanocomposite material is an advanced platform that exhibits Graphene-mediated Surface-Enhanced Raman Scattering. The sensing layers have been prepared via sol-gel process and imprinted with rhodamine 6G to obtain selective dye recognition. Graphene oxide sheets decorated with silver nanoparticles have been incorporated into the matrix to enhance the Raman scattering signal. The template molecule can be easily removed from the films by ultrasonication in ethanol. A 712-fold Raman enhancement has been observed, which corresponds to a 2.15 × 1013 count·μmol−1 signal enhancement per molecular cavity. Besides Raman enhancement, the sensing platform has shown an excellent selectivity toward the test molecule with respect to similar dyes. In addition, the material can be reused at least 10 times without any loss of performance.

This paper presents the dielectric characteristics of nanocomposite films of poly(vinyl alcohol) (PVA) embedded with silver (Ag) nanoparticles and graphene oxide(GO). The nanocomposite films were fabricated by using the solvent casting approach. The morphological analysis was carried out through scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The dielectric relaxation behavior of nanocomposite films was analyzed in the frequency range of 101 to 106 Hz, by varying GO loading. The temperature effect was investigated over the temperature range of 40 to 150 °C. The effect of ionic liquid (IL) was also explored by comparing the dielectric behavior of films fabricated without using ionic liquid. The conductive filler loading variation showed a significant effect on dielectric permittivity(ε′), complex impedance (Z*) and electric conductivity (σac). The obtained results revealed that the dielectric permittivity (ε′) increased by incorporating Ag nanoparticles and increasing GO loading in PVA matrix. An incremental trend in dielectric permittivity was observed on increasing the temperature, which is attributed to tunneling and hopping mechanism. With an increase in nanofiller loading, the real part of impedance (Z′) and imaginary part of impedance (Z″) were found to decrease. Further, the semicircular nature of Nyquist plot indicated the decrease in bulk resistivity on increasing GO loading, temperature and incorporating ionic liquid. On the basis of above findings, the obtained GO-Ag-PVA nanocomposite films can find promising applications in charge storage devices.

The electrodeposition of graphene has drawn considerable attention due to its appealing applications for sensors, supercapacitors and lithium-ion batteries. However, there are still some limitations in the current electrodeposition methods for graphene. Here, we present a novel electrodeposition method for the direct deposition of reduced graphene oxide (rGO) with chitosan. In this method, a 2-hydroxypropyltrimethylammonium chloride-based chitosan-modified rGO material was prepared. This material disperses homogenously in the chitosan solution, forming a deposition solution with good dispersion stability. Subsequently, the modified rGO material was deposited on an electrode through codeposition with chitosan, based on the coordination deposition method. After electrodeposition, the homogeneous, deposited rGO/chitosan films can be generated on copper or silver electrodes or substrates. The electrodeposition method allows for the convenient and controlled creation of rGO/chitosan nanocomposite coatings and films of different shapes and thickness. It also introduces a new method of creating films, as they can be peeled completely from the electrodes. Moreover, this method allows for a rGO/chitosan film to be deposited directly onto an electrode, which can then be used for electrochemical detection.

Silver-functionalized reduced graphene oxide (Ag-rGO) nanosheets were prepared by single chemical and thermal processes, with very low concentration of silver. The resulting carbon framework consists of reduced graphene oxide (rGO) sheets or 3D networks, decorated with anchored silver nanoparticles. The Ag-rGO nanosheets were dispersed into a polymer matrix and the composites evaluated for use as biological scaffolds. The rGO material in poly(dimethylsiloxane) (PDMS) has been tested for antimicrobial activity against Gram-positiveStaphylococcus aureus(S. Aureus) bacteria, after exposure times of 24 and 120 hours, as well as in the determination of cell viability on cultures of fibroblast cells (NIH/3T3). Using 1 mL of Ag-rGO in PDMS the antibacterial effectiveness againstStaphylococcus aureuswas limited, showing an increased amount of Colony Forming Units (CFU), after 24 hours of contact. In the cell viability assay, after 48 hours of contact, the group of 1 mL of Ag-rGO with PDMS was the only group that increased cell viability when compared to the control group. In this context, it is believed these behaviors are due to the increase in cell adhesion capacity promoted by the rGO. Thus, the Ag-rGO/PDMS hybrid nanocomposite films can be used as scaffolds for tissue engineering, as they limit antimicrobial activity.

The ternary nanocomposite of silver particles decorated N/S dual-doped graphene and molybdenum disulfide microspheres (Ag-MoS2/NSG) is prepared by hydrothermal-chemical reduction method with graphene quantum dots (GQDs) as additives and graphene oxide, sodium molybdate and silver nitrate as main raw materials. For comparison, the binary composites of Ag-MoS2, Ag-NSG and MoS2/NSG are also prepared and discussed. In addition, the physicochemical and electrochemical properties of GQDs are studied, and the dynamic analysis of Ag-MoS2/NSG is also carried out. Results show that the ternary composite of Ag, MoS2 and NSG can effectively prevent the lamellar superposition and agglomeration of graphene, which effectively improves the specific surface area and conductive properties of the composite. The specific capacitance of Ag-MoS2/NSG is 1124.3 F·g−1 at 10 mV·s−1, and the specific capacitance retention is 95.2% after 10000 constant current charge/discharge loops. The asymmetric button supercapacitor device assembled with NSG and Ag-MoS2/NSG has a maximum energy density of 82.5 Wh·kg−1 (900 W·kg−1).

Nanocomposites of poly (BA/MMA) reinforced with up to 3 wt % grahene sheets were used as targets for laser ablation. The target was ablated using TEA CO2 laser with fluence of 1,00 J/cm2 and thin films of crosslinked polymer/graphene with large specific surface area were obtained. The polymer-graphene deposit was covered with silver nanoparticles by excimer laser ablation in order to prepare active substrates for Surface-Enhanced Raman Scattering (SERS). The nanocomposites were characterized by means of spectroscopy, microscopy and diffraction techniques. The SERS substrate performance was tested using Rhodamine 6G as a probe compound. Highly enhanced signal was achieved, and sensoric properties of the prepared substrates were demonstrated.

Polymer nanocomposites containing nanometals became a subject of interest due to their bactericidal properties. Different polysaccharides have been used as matrices for nanosilver and nanogold synthesis. In this study, we present a novel, environmentally friendly method for the preparation of sodium alginate/nanosilver/graphene oxide (GOX) and sodium alginate/nanogold/graphene oxide GOX nanocomposites and their characteristics. The formation of approximately 10–20 nm ball-shaped Ag and Au nanoparticles was confirmed by UV–vis spectroscopy, scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectra. The incorporation of GOX sheets within the ALG matrix improved the thermal stability of the nanocomposites film, which was measured using the differential scanning calorimetry (DSC). We also estimated the molecular weights of polysaccharide chains of the matrix with the size exclusion chromatography coupled with multiangle laser light scattering and refractometric detectors (HPSEC-MALLS-RI). The composites were more prone to enzymatic hydrolysis. The strongest bacteriostatic activity was observed for the sample containing nanosilver.

The over prescribing of broad-spectrum antibiotics has given rise to the multidrug resistance in bacteria. The antimicrobial resistance caused the medicines and treatments to become ineffective and became difficult to treat infection. In order to avoid the overuse of antibiotics, antibacterial material have been developed and applied in preventing bacterial infection, drug delivery, and medical implant. Nanomaterials materials show great potential in many applications [1-33]. Therefore, in our study, we designed nanosilica islands on graphene oxide template to disperse the silver nanoparticles and improve its antibacterial properties. Silver nanoparticles have been known for its exceptional antimicrobial properties. However, some bacteria were able to use their flagellum to cause the silver nanoparticles agglomerated. By using silica nanoparticles and graphene oxide, we not only avoid the agglomerated issues but also improve the antibacterial ability of the material. Our novel composite was characterized by using Powder X-Ray Diffraction (P-XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Tranmission electron microscopy (TEM), and Fourier Transform Infrared (FTIR). The silica nanoparticles and graphene template helped to form dispersed nanoparticles of 7 nm. The composite successfully eliminated 99.99% of Escherichia coli and Bacillus Subtilis within one hour.

Abstract Although transparent conductive oxides such as indium tin oxide (ITO) are widely employed as transparent conducting electrodes (TCEs) for applications such as touch screens and displays, new nanostructured TCEs are of interest for future applications, including emerging transparent and flexible electronics. A number of twodimensional networks of nanostructured elements have been reported, including metallic nanowire networks consisting of silver nanowires, metallic carbon nanotubes (m-CNTs), copper nanowires or gold nanowires, and metallic mesh structures. In these single-component systems, it has generally been difficult to achieve sheet resistances that are comparable to ITO at a given broadband optical transparency. A relatively new third category of TCEs consisting of networks of 1D-1D and 1D-2D nanocomposites (such as silver nanowires and CNTs, silver nanowires and polycrystalline graphene, silver nanowires and reduced graphene oxide) have demonstrated TCE performance comparable to, or better than, ITO. In such hybrid networks, copercolation between the two components can lead to relatively low sheet resistances at nanowire densities corresponding to high optical transmittance. This review provides an overview of reported hybrid networks, including a comparison of the performance regimes achievable with those of ITO and single-component nanostructured networks. The performance is compared to that expected from bulk thin films and analyzed in terms of the copercolation model. In addition, performance characteristics relevant for flexible and transparent applications are discussed. The new TCEs are promising, but significant work must be done to ensure earth abundance, stability, and reliability so that they can eventually replace traditional ITO-based transparent conductors.

Purpose This paper aims to report the tribological behavior of Ag nanoparticles/reduced graphene oxide nanocomposites (Ag/RGO NCs) and Ag nanoparticles (Ag NPs) as a green additive in oil with different concentration and under different friction conditions. Design/methodology/approach The Ag/RGO NCs and Ag NPs were both synthesized in a chemical reduction method. The diameter of silver nanoparticles implanted between RGO sheets was about 25 nm and that of silver sol was 70 nm. The morphology and structure of Ag/RGO NC were characterized by TEM, XRD and FTIR. The tribological properties of Ag/RGO NCs and Ag NPs as lubricant oil additive were evaluated by measuring the friction coefficients and wear of the surface in different condition which were tested on UMT-II. Findings The results indicated that both the additives improved the friction-reduced and anti-wear properties of paraffin oil, and Ag/RGO NCs has better tribological performance than Ag NPs. The excellent tribological properties were attributed to the special structure of Ag/RGO NC and the formation of tribofilm reducing the friction and wear on the shearing surfaces. Research limitations/implications It is relatively difficult to observe the morphology of the lubricant film formed on the friction surface and to analyze the chemical composition at different depths of the lubricant film. Originality/value It is the first time for Ag/RGO NCs to be applied to improve the friction-reduced and anti-wear properties of lubricant oil as additive.

In this project, we report on the prepare of nickel oxide nanoparticles (NiO NPs) via a photolysis method using UV lamb followed by calcination at 400 C for 3 h. the synthesized Nano-powder were investigated field emission scanning electron microscope (FE-SEM), photoluminescence spectroscopy (PL) and X-ray diffraction (XRD). The SEM image confirmed the crystal structure of the synthesized NiO nanoparticles with an average particle size of 23 nm, and the XRD analysis revealed the absence of impurity peaks. The optical properties were analyzed using photoluminescence spectroscopy (PL), and the bandgap was determined to be 3.4 eV. The semiconductor property, which can be exploited for solar cell applications, is responsible for the broad bandgap. To make dyesensitized solar cells (DSSC), we used photo-chemically synthesized NiO NPs as a photoanode. Two counter electrode were used in this study: Graphene oxide Nano-Sheets and Graphene oxide\silver nanocomposite. cibacron brilliant red B is one of the dyes that are used in the textile factory of Wasit Governorate, and the rest of it is often discarded as waste water Which we used in our study as a photosensitizer. The open-circuit voltage (Voc), short t current density (Jsc), fill factor (FF), and efficiency (h) were determined from the J-V curves, where efficiency was between 0.231 to 1.47 %, at 100 mW/cm2. Finally, it can be confirmed that the presence of nickel oxide nanoparticles with a cibacron brilliant red B dye can improve the performance of dye-sensitized solar cells.

This article provides an overview of current research into the development, synthesis, photocatalytic bacterial activity, biocompatibility and cytotoxic properties of various visible-light active titanium dioxide (TiO2) nanoparticles (NPs) and their nanocomposites. To achieve antibacterial inactivation under visible light, TiO2 NPs are doped with metal and non-metal elements, modified with carbonaceous nanomaterials, and coupled with other metal oxide semiconductors. Transition metals introduce a localized d-electron state just below the conduction band of TiO2 NPs, thereby narrowing the bandgap and causing a red shift of the optical absorption edge into the visible region. Silver nanoparticles of doped TiO2 NPs experience surface plasmon resonance under visible light excitation, leading to the injection of hot electrons into the conduction band of TiO2 NPs to generate reactive oxygen species (ROS) for bacterial killing. The modification of TiO2 NPs with carbon nanotubes and graphene sheets also achieve the efficient creation of ROS under visible light irradiation. Furthermore, titanium-based alloy implants in orthopedics with enhanced antibacterial activity and biocompatibility can be achieved by forming a surface layer of Ag-doped titania nanotubes. By incorporating TiO2 NPs and Cu-doped TiO2 NPs into chitosan or the textile matrix, the resulting polymer nanocomposites exhibit excellent antimicrobial properties that can have applications as fruit/food wrapping films, self-cleaning fabrics, medical scaffolds and wound dressings. Considering the possible use of visible-light active TiO2 nanomaterials for various applications, their toxicity impact on the environment and public health is also addressed.

For wound healing, functional films with certain physicochemical and biological properties are needed. Thus, the current work aimed to fabricate multifunctional materials comprising metal oxide nanoparticles loaded with an efficient polymer to be used as dressing material. A composite containing polymeric phases of cellulose acetate (CA) blended with zinc sulfide (ZnS), silver oxide (Ag2O), and graphene oxide (GO) was successfully synthesized. The prepared composite crystallinity was studied using the X-ray diffraction technique (XRD). Further, the functional groups and the elemental analysis were investigated using Fourier-transform infrared spectroscopy (FTIR) and energy-dispersive X-ray spectroscopy (EDX). Furthermore, the surface morphology was studied using scanning electron microscopy (SEM) to obtain the shape and size of particles. SEM showed that the particles were formed in wide distribution in the range of 18–915 nm with an average size of 235 nm for Ag2O/ZnS/GO/CA. The particle size of Ag2O in the CA film was in the range between 19 and 648 nm with an average size of 216 nm, while the particle size of ZnS in CA was in the range of 12–991 nm with an average age particle size of 158 mm. In addition, EDX, based on SEM investigation, detected high carbon and oxygen quantities at around 94.21% of the composite. The contact angle decreased and reached 26.28° ± 2.12° in Ag2O/ZnS/CA. Furthermore, thermogravimetric analysis (TGA) was used to investigate the thermal stability, and the composition was thermally stable until 300 °C. Moreover, the cell viability of “normal lung cells” reached 102.66% in vitro at a concentration of 1250 µg/mL. The antibacterial activity of Ag2O/ZnS/GO/CA was also detected against E. coli with a zone of inhibition reaching 17.7 ± 0.5 mm. Therefore, the composite can be used in biomedical applications due to its biocompatibility and antibacterial activity.

In this work, plasmon characteristics of nanocomposite materials based on graphene, graphene oxide, and silver nanoparticles have been studied. The effective dielectric constant and absorption coefficient of the nanocomposites based on graphene-silver and graphene oxide – silver depending on the concentration and size of nanoparticles have been calculated. A change in the silver nanoparticles filling factor by 5 percent leads to significant changes in both the real and imaginary parts of the effective dielectric constant of the nanocomposite material. A pronounced absorption peak is observed in the case of graphene-based nanocomposite with a silver filling factor of 0.2. At the same time, the absorption peak can be indicated at a silver filling factor of 0.1 for the graphene oxide-based nanocomposite. The maximum absorption is observed for the nanocomposite material with nanoparticles having a radius of 5 nm in both cases. The researched nanocomposite materials can be successfully used for various organic electronics applications.

Graphene oxide (GO) sheets, a single layer of carbon atoms which can be served as substrates for fabricating metallic nanoparticles-GO nanocomposites. In this study, the nanocomposite of silver nanoparticles and graphene oxide were produced via in-situ synthesis and with the addition of chitosan to investigate the formation of silver nanoparticles on the graphene oxide sheets. XRD and UV-Vis studies confirmed the formation of silver nanoparticles on GO sheets, while TEM and FESEM images presented the loading of silver nanoparticles on the GO sheets. The degree of loading and distribution of the silver nanoparticles on the graphene oxide were depend on the method during the formation of silver nanoparticles. The nanocomposites can be potentially used in food packaging and biomedical applications.

A novel approach for the synthesis of graphene oxide silver alginate has been developed for the antibacterial performance. Graphene oxide (GO) was used as a supporting material towards formation of silver nanoparticle (AgNPs) by a rapid microwave irradiation on mixture of GO and silver complexes and layered on alginate film. The obtained nanocomposite were characterized by using Ultraviolet-visible spectroscopy (UV-Vis), Xray diffraction (XRD) to confirm the formation of GOAgAlginate. The surface morphological studies for the nanocomposite was done by using scanning electron microscope (SEM). Nanometer-sized AgNPs (an average diameter of about 70 nm) with spherical-shape structure loaded on the GO Alginate layer showed a good antibacterial towards E.Coli and Methicillin-resistant Staphylococcus aureus (MRSA).

Herein, we report for the first time, the synthesis of silver nanoparticles-nitrogen doped graphene oxide-chitosan nanocomposite (SGC) from the aqueous leaf extract of Curcuma caesia plant and we explored bacterial toxicology behavior of SGC nanocomposite via agar disc diffusion method. Curcuma caesia is a medicinal herb utilized as a reducing agent for the reduction of silver-to-silver ions. Graphene oxide is a significant two-dimensional carbon nanomaterial, possessing excellent physical, chemical, and electrical properties that make them unique for various applications. The Ultrasonication process at room temperature was utilized for the synthesis of SGC nanocomposite. The addition of biopolymer; chitosan, and silver nanoparticles (AgNPs) to the matrix of nitrogen-doped graphene oxide (NGO) was confirmed via various spectroscopic techniques such as FTIR, FT-Raman, XPS, and so on. Finally, the results of the disc diffusion method showed SGC nanocomposite exhibit concentration-dependent inhibition toward bacterial growth.

Silver nanoparticles (AgNPs) were deposited onto surface-hydrolysed PET film by an electrostatic self-assembly technique, so as to fabricate multilayer nanocomposite films. The self-assembly process was monitored by ultraviolet-visible (UV-Vis) spectroscopy. The surface morphology and chemical composition of the multilayer nanocomposite films were characterised by Field Emission Scanning Electron Microscopy (FESEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The results showed that the AgNPs were uniformly dispersed on the PET film, in the metallic silver state. The thermal stability of the multilayer nanocomposite films was investigated by thermogravimetric analysis (TGA), and it was found that the presence of AgNPs on the surface of PET enhanced the thermal stability of the PET film. The antibacterial performance of the multilayer nanocomposite films was investigated by staphylococcus aureus to monitor the number of the bacterial cells. The results suggested that the PET films after assembled 10-bilayer PDDA/AgNPs multilayer films exhibited good antibacterial performance.
