Full textThe incorporation of inorganic particles into a polymer matrix confers new properties to the material or enhances significantly existing properties. However, the perceived visual appearance, such as loss of transparency, might be modified by the scattering of light by the particles. This light scattering is mainly due to the particle –or aggregates of particles- dimensions and the refractive index difference between matrix and fillers. In order to address both issues, the objective of the present work was to control simultaneously the dispersion state of the inorganic nanoparticles into the polymeric matrix and the refractive index of the nanoparticles to match the one of the matrix. To achieve this new composite, we designed hybrid core@shell nanoparticles with an inorganic core that brings new properties and a polymer shell of controlled thickness, obtained by surface-initiated nitroxide mediated controlled radical polymerization. The polymer shell limits the aggregation of the particles and enables us to tune the average refractive index of the hybrid core@shell particle. By controlling the thickness and the chemical nature of the polymeric shell, we targeted to match the refractive index of the hybrid core@shell particle to the one of the polymeric matrix. The nanoparticles were further dispersed into a poly(methyl methacrylate) matrix. Optical properties of composites were characterized by spectrogoniophotometry which gave us informations about the intensity and the angular distribution of the transmitted light by the nanocomposites. The transparency of the nanocomposites was strongly enhanced for core@shell particles fulfilling the refractive index matching conditions

Full textNew materials based on silica oxides (mesoporous silica SBA-15, magnetic core-shell nanoparticles) combined with nucleophilic hybrids of (vacant) polyoxometalates were elaborated for applications in the field of anchored homogeneous catalysis for mild oxidations reactions. The main parameter taken into account was the formation of a covalent bond between the support and the POMs. Two different pathways were followed depending upon the support used for the covalently grafting of POMs. Firstly, Keggin type POMs bearing carboxylic acid functions were grafted onto amino-functionalized SBA-15. Using the same support, other covalent immobilization methods were tried out, such as the use of a cross-linker. Secondly, hybrid nanocatalysts based on magnetic core-shell nanoparticles grafted with POMs were synthesized. All materials were characterized by a wide variety of physicochemical techniques. By HR TEM, the POMs were localized inside the pores of SBA-15 and onto the surface of magnetic core shell NPs, showing an excellent nanostructuration on the surface of both materials. Furthermore, the catalytic activity of the synthesized anchored homogeneous catalysts has been evaluated through the epoxidation of cyclooctene and cyclohenexe with H2O2 in acetonitrile, resulting in fairly good conversions in some cases, compared to the homogeneous systems used in this study. Finally, particular attention was paid to the excellent catalytic behavior of POMs bearing carboxylic acid functions compared to other POMs of the same family. Thus, DFT calculations were performed in order to identify the cause of this enhanced reactivity

Full textThe everlasting search for the miniaturization of the processes has shown that at the nanometer scale materials exhibit different properties than from the bulk. Today, the synthesis of nano-sized objects is in perfect harmony with biological systems for medical applications. The opportunity for chemists to combine into a single nano-oject different kind of materials with complementary properties has opened the way for the development of multifunctional nanoparticles for biological applications. In this area, using the remarkable properties of rare earths, LPCML laboratory from Lyon University in collaboration with MATEIS laboratory from INSA-Lyon was able to develop multifunctional hybrid nanoparticles with a core/shell structure by combining an inorganic rare earth oxide core coated by a polysiloxane shell. The using of a lanthanide in the core enables the combination of detection tools (optical with Eu and Tb, MRI with Gd, Dy and Ho or scintigraphy with Ho) and therapeutic agents with Gd and Ho. After having studied the properties of gadolinium as a contrast and neutron capture therapeutic agent, we were interested in atomic properties of holmium after neutron irradiation which emits and - radiations, potentially interesting for scintigraphic imaging and brachytherapy. The thesis presented here reports studies on the one hand on optical and magnetic properties of these hybrid nanoparticles and on the other hand the possibilities of medical applications by using holmium-based particles

Full textNowadays, in the field of nanomedecine, the major challenge is to design multifunctional nanomaterials in order to improve diagnosis and treatment efficiency. In this context, our work has concerned the conception of hybrid Au@SiO2 core-shell nanoparticles combining the photothermal properties of the gold core and the drug delivery function associated with the inorganic porous network. The entrance pore functionalization with gatekeepers leads finally to mecanized nanosystems. The first part of the work has concerned the core material synthesis (hollow gold nanoparticles called « nanoshells ») which has been achieved by a galvanic replacement reaction. The influence of synthesis parameters on the structure, the morphology and on the optical properties has been studied. Moreover, the analysis of a nanoparticle cross-section by XPS and AES has evidenced the formation of a heterogeneous Ag-Au alloy. Then, the growth of a mesoporous silica shell on the metal cores has been conducted leading to Au@SiO2 nanomaterials. After demonstrating the potential of these core-shell nanoparticles for hosting molecules, the nano-objects have been functionalized with supramolecular nanovalves based on a diaminoalkoxysilane (grafted on the silica surface) interacting with a macrocycle. The combination of XPS and NMR allowed us to characterize precisely the functionalization. In a last section, we have been interested in the design of biocompatible systems with the elaboration of a hybrid polymer/silica shell. The in vitro effect and interaction of nanoparticles with HaCaT cells have been studied; the first results have demonstrated a real interest for using poly-L-lysine in these systems. This original study offers new details about the physico-chemical characterization of nanostructured systems which highlights the important role of interfaces in hybrid materials. The perspectives will concern the optimization of the synthesized nanosystems for direct nanomedicine applications

Full textThe thesis is devoted to the synthesis and investigation of properties of inorganic-organic polyaniline (PANI) and polypyrrole (PPy) based hybrid materials with TiO2 (rutile and anatase) and SnO2 nanoparticles applicable for ammonia and amines detection. The direct polymer growth on the surface of nanoparticles allowed obtaining of nanocomposite materials with a “core-shell” structure which differs from simple mechanical mixture by more uniform polymer distribution and stronger interaction between source components.The object of research is the process of formation of polyaniline and polypyrrole nanocomposites with metal oxides. The research goal is to reveal formation peculiarities and properties of nanostructured composite materials based on conducting polymers and metal oxides nanoparticles that are sensitive to ammonia and amines. Research methods include RedOx and pH monitoring, FTIR and UV-spectroscopy, SEM, TEM, thermogravimetry, liquid chromatography, conductivity measurements and sensor tests.The new approach to study kinetics of aniline polymerization process by simultaneous RedOx and pH monitoring of reaction medium was proposed. For the first time the influence of sulfonic acids and metal oxides on the aniline polymerization process and molecular characteristics of the obtained polymer was shown. For the first time a linear correlation between the nanoparticles content and reciprocal duration of separate stages of polymerization was shown. Formed "core-shell" nanocomposites have sensitivity to ammonia and amines of about 2 times higher than the pure polymer. Developed new materials can be used in the manufacturing of chemoresistive sensors' active layers

Full textNanocomposite materials present unique physic-chemical properties that cannot be obtained using one component. Thus, the improvement in the properties of such materials have resulted in major interest for versatile fields. Dielectric nanocomposite materials with high energy density exhibit promising performances for energy storage applications. Major efforts have been conducted to combine the efficient properties and high dielectric constant of ceramics with the flexibility and easy processing of polymers. Thus, this thesis focuses on the development and characterizations of nanocomposites based on BaTiO3 ceramic and fluoropolymers. First, the synthesis of PVDF-g-BaTiO3 was realized using RAFT polymerization of VDF from the surface of functionalized nanoparticles, using different BaTiO3 concentrations, and the effect of such percentage on the final properties was studied. Results showed the successful grafting of PVDF leading to nanocomposites with enhanced thermal stability. Furthermore, the successful grafting of PVDF onto the functionalized nanoparticles was mainly proved by HRMAS NMR spectroscopy, which was used for the first time to characterize the prepared nanocomposites. The dielectric properties of such materials were investigated, and reveals the existence of three relaxations: the first one was attributed to the well-known β secondary relaxation in PVDF, the second one was assigned to the crystalline fraction in the polymer, while the third relaxation was assigned to interfacial polarization arising from the presence of fillers and impurities in the system. However, the relaxation related to glass transition temperature could not be observed due to the high crystallinity of the polymer. Solution blending strategy was also used to prepare nanocomposite materials consisting of PVDF-g-BaTiO3/P(VDF-co-HFP) and the prepared films were fully characterized. The uniform distribution of PVDF-g-BaTiO3 nanocomposites in the copolymer matrix leads to enhanced mechanical performances resulting in increased Young’s modulus. Then, to supply an application for the prepared PVDF-g-BaTiO3 nanocomposites, those later were used as binder to prepare cathode material for batteries. Calendering procedure was used to prepare the electrode films and enabled to obtain uniform structure and enhanced cycling performances

Full textThe aim of this PhD work was to synthesize and test new nano-objects for the diagnosis and treatment of cancer. For this purpose, we developed hybrid nanoparticles made of an inorganic core surrounded by a human serum albumin (HSA) organic coating. The inorganic core is a composite by itself as it is made of an iron oxide core (IO) surrounded by a mesoporous silica (MS) shell. The IO core ensures, through its magnetic properties, diagnosis by magnetic resonance imaging (MRI) and therapy by magnetic hyperthermia, whereas the MS shell allows the loading of anticancer drugs for chemotherapy within its porosities. The pore sizes of the silica shell were modulated to enhance the drug loading content and the IO core size was also tuned to improve magnetic hyperthermia as well as T2 MRI imaging properties of the final core-shell system. The use of a thick shell of HSA as gatekeeper for controlled drug delivery triggered by its degradation with proteases was also studied. In parallel the synthesis of drug loaded HSA nanocapsules using MS as sacrificial template was performed. Finally, the biological activities of these nanoparticles were tested on various cancer cell lines
