Ce travail examine le potentiel du procédé jet d'encre pour fabriquer des composants électroniques à bas coût. Trois axes de recherche sont explorés: (i) supports, (H) encres conductrices, et (iii) procédé. Les propriétés de surface du support comme la rugosité ou l'énergie de surface apparaissent comme des paramètres fondamentaux influençant la conductivité des pistes imprimées. Une pré-couche pour adapter les supports papiers avec l'électronique imprimée a donc été proposée. Des traitements alternatifs de frittage des encres nanométalliques ont été testés et de nouvelles encres conductrices à base de nanotubes de carbone (NTC) et de pOlymères conducteurs ont été formulées. Ces encres à base de NTC ont été étudiées plus en détail par l'analyse de l'influence du procédé d'impression et son impact sur les performances et l'organisation du réseau de NTCs. Cette étude donne de nouvelles possibilités pour l'électronique imprimée et ouvre la route à de nouvelles applications bas coûtThis work investigates the inkjet printing process to print conductive patterns for producing low cost electronic components. Three fields were explored: (i) substrates, (ii) conductive inks, and (iii) process. Substrate surface properties su ch as roughness or surface energy have a significant impact on conductivity of printed tracks. An innovative solution to make any paper suitable for printed electronics has then been proposed. Infrared and electrical treatments were tested as potential sintering alternatives of nanometallic inks, and new conductive inks based on carbon nanotubes (CNT) and conductive polymers were formulated. This new CNT-based ink has been studied more in details by analyzing influence of inkjet printing parameters and their impact on the CNT network organization and on the conductivity. This study represents an important step in the field of printing electronics, and also opens windows to new low cost applications such as smart packaging or flexible electronics

Additive manufacturing processes, which utilize selective deposition of material rather than traditional subtractive methods, are very promising due to their ability to build complex, highly specific geometries in short periods of time. Three-dimensional direct inkjet printing is a relatively new additive process that promises to be more efficient, scalable, and financially feasible than others. Due to its novelty, however, numerous technical challenges remain to be overcome before it can attain widespread use. This thesis identifies those challenges and finds that material limitations are the most critical at this point. In the case of deposition of high viscosity polymers, for example, it is found that droplet formation is a limiting factor.
Acoustic resonance jetting, a technology recently developed at Georgia Institute of Technology, may have the potential to address this limitation because it generates droplets using a physical mechanism different from those currently in use. This process focuses ultrasonic waves using cavity resonances to form a standing wave with high pressure gradients near the orifice of the nozzle, thereby ejecting droplets periodically. This thesis reports initial exploratory testing of this technologys performance with various material and process parameters. In addition, analytical and numerical analyses of the physical phenomena are presented. Results show that, while the pressures generated by the system are significant, energy losses due to viscous friction within the nozzle may prove to be prohibitive. This thesis identifies and begins evaluation of many of the process variables, providing a strong basis for continued investigation of this technology.

Published ArticleThis paper surveys the current state and capabilities of Three Dimensional Printing (3DP). Based on its technical background - the ink jet printing as known from the printer and plotter industry - a classification structure has been developed and proposed. Different printing techniques and process concepts, together with their advantages and limitations are described and analysed. A large variety of manufacturing applications such as rapid pattern making and rapid tooling using the 3DP process directly or as core technology, as well as further implications in design and engineering analysis, medicine, and architecture are presented and evaluated. Some research issues are also discussed. An attempt, based on the state of the art, to show weaknesses and opportunities, and to draw conclusions about the future of this important process wraps up this paper.

Low profile, conformal antennas have considerable advantages for Aerospace and Military platforms where conventional antenna system add weight and drag. Direct Write (DW) technology has been earmarked as a potential method for fabricating low profile antennas directly onto structural components. This thesis determines the key design rules and requirements for DW fabrication of planar antennas. From this, three key areas were investigated: the characterisation of DW ink materials for functionality and durability in harsh environments, localised processing of DW inks and the optimisation of DW conductive ink material properties for antenna fabrication. This study mainly focused on established DW technologies such as micro-nozzle and inkjet printing due to their ability to print on conformal surfaces. From initial characterisation studies it was found that silver based micro-nozzle PTF inks had greater adhesion then silver nano-particle inkjet inks but had lower conductivity (2% bulk conductivity of silver as opposed to 8% bulk conductivity). At higher curing temperatures (>300??C) inkjet inks were able to achieve conductivities of 33% bulk conductivity of silver. However, these temperatures were not suitable for processing on temperature sensitive surfaces such as carbon fibre. Durability tests showed that silver PTF inks were able to withstand standard aerospace environments apart from Skydrol immersion. It was found that DW inks should achieve a minimum conductivity of 30% bulk silver to reduce antenna and transmission line losses. Using a localised electroplating process (known as brush plating) it was shown that a copper layer could be deposited onto silver inkjet inks and thermoplastic PTF inks with a copper layer exhibiting a bulk conductivity of 66% bulk copper and 57% bulk copper respectively. This was an improvement on previous electroless plating techniques which reported bulk copper conductivities of 50% whilst also enabling DW inks to be plated without the need for a chemical bath. One of the limitations of many DW ink materials is they require curing or sintering before they become functional. Conventional heat treatment is performed using an oven which is not suitable when processing DW materials onto large structural component. Previous literature has investigated laser curing as means of overcoming this problem. However, lasers are monochromatic and can therefore be inefficient when curing materials that have absorption bands that differ from the laser wavelength. To investigate this, a laser diode system was compared to a broadband spot curing system. In the curing trials it was found that silver inks could be cured with much lower energy density (by a factor of 10) using the broadband white light source. Spectroscopy also revealed that broadband curing could be more advantageous when curing DW dielectric ink materials as these inks absorb at multiple wavelengths but have low heat conductivity. Themodynamical modelling of the curing process with the broadband heat source was also performed. Using this model it was shown that the parameters required to cure the ink with the broadband heat source only caused heat penetration by a few hundred micro-metres into the top surface of the substrate at very short exposure times (~1s). This suggested that this curing method could be used to process the DW inks on temperature sensitive materials without causing any significant damage. Using a combination of the developments made in this thesis the RF properties of the DW inks were measured after broadband curing and copper plating. It was found that the copper plated DW ink tracks gave an equivalent transmission line loss to a copper etched line. To test this further a number of GPS patch antennas were fabricated out of the DW ink materials. Again the copper plated antenna gave similar properties to the copper etched antenna. To demonstrate the printing capabilities of the micro-nozzle system a mock wireless telecommunications antenna was fabricated on to a GRP UAV wing. In this demonstrator a dielectric and conductive antenna pattern was fabricated on to the leading edge of the wing component using a combination of convection curing and laser curing (using an 808nm diode laser).

The color filter (CF) has been one of the most important components for full-color active matrix LCD panel. An emerging process for manufacturing CF has been technically developed by an inkjet printing system. Inkjet printing process for color filter fabrication is key technology for next generation process. To prevent ink overflow from the black matrices (BM) bank, two effective surface treatments are introduced in this thesis. Because the color ink is jetting on glass substrates with black matrices (BM), the total jetting droplet’s volume will overflow from one bank to another if the volume is much larger than the bank. Increase contact angle of drops on BM to make color ink not wetting and to prevent ink overflow from the BM bank. The contact angle of drops on chemical treated and CFx plasma treated BM are increased. In this thesis, we also use the Litrex 70L ink-jet printing system to print red, green, and blue single color films. And we also combined the red, green, and blue color films to form a three-color films BM.

In recent years, flat panel display (LCD, OLED, PDP, FED, etc.) is very popular. The many companies and research center is planning to develop the next generation technology of display. Especially, color filter is the important components in LCD’s supply chain. They always use the spin and slit coating technology to approach this process currently. But the spin and slit coating always wasted much material(~98%), clean process is highly requirement to environment in the future. In addition, traditional method is difficult to cover resist on the large substrate smoothly. Using ink-jet printing technology, we just print out ink to the required area of color filter. So compare to traditional technology, the material will save much a lot. It will be an excellent process, and friendly to environment. The paper is used ink of photo spacer printing on the ITO substrate. By contact angle measurement, we study the interface effect of spacer material and substrate. According to the results, we improve the substrate surface character by different chemical treatment. The wall and area of color filter is necessary with difference surface character. We split many of condition to find the relationship of hydrophilic between the material and substrate and hydrophobic between wall and substrate. It is the best condition to print ink on ITO substrate. And also we obtain important parameter for ink-jet equipment by variation of frequency, voltage and ink head size, respectively. In conclusion, the new display technology by inkjet printing system is feasible in the future. Many of company have pay much attention to develop ink-jet process. We believe the mass production equipment will be appeared on next generation LCD fab.

A commercial ink-jet printer was employed and the cartridge was filled with various catalytic solutions to find optimal conditions and catalytic species. As a result, carbon nanomaterials, including carbon nanofibers, carbon nanocoils, MWNTs, and bamboo-like CNTs, were grown by CVD method under the presence of Ni catalysts at various temperatures. FE-SEM and HR-TEM were used to examine the morphologies, dimensions, graphitic structures of carbon nanomaterials, respectively. In addition, J-E and F-N curves of CNFs were measured by Keithley 237 and the result showed that the turn-on voltage for field emission was in the range of 3.05~3.37 V/μm(10μA/cm2) and the largest current density is 5mA/cm2 at 4.3V/μm.

The inkjet printing technology, for large-scale use of piezoelectric jet technology and research, will be introduced in this study. There are several main technical advantages, which consist of the ability to get big size and uniform area, quickly define figure type, have high resolution capabilities, and faster film-forming process speed, for the piezoelectric type inkjet printing technology. In addition, the adjustable parameters and voltage can achieve more accurate ink jet and also reduce the loss of material. We can use its advantages to discover this study. In the study of quickly define figure type, which can be used in the place of Photolithography, the ink droplets of Au nanoparticles (AuNP) 10~15nm solution are utilized in this study and the ITO surface are adjusted by the use of surface modification treatment. The ITO glass substrates are immersed and soaked in the hydrochloric acid solutions with different proportions, so that the suface contact angle between ITO thin-film electrodes and AuNP ink droplets can be improved to demonstrate the hydrophilic surface (10° < θ < 80°). In the inkjet printing process, AuNP ink droplets can be uniformly diffused, so that the ink droplets can overlap. The inkjet printing with the use of Au nanoparticles (AuNP) 10~15nm can be applied in the basic structure of the OLED optoelectronic devices. First, the Au nanoparticles (AuNP) can be inkjet printed directly onto the surface-modified ITO glass substrates. Then a conventional structure of green OLED can be further prepared by using thermal evaporation system. The related optoelectronic characteristics can be measured and analysed. Due to the fact that the particle size of the used Au nanoparticles (AuNP) solution is less than 100nm, it exhibit wine red. However, the surface plasma resonance absorption wavelength of the gold nano-spheres are distributed in the range of 510−535nm according to the different sizes (10 to 25nm). In the literature, the working potential of Au nanoparticles (AuNP) with the particle size of approximate 5~25nm is in the HOMO of 5.1 to 5.2 eV, while the working potential of the ITO thin film electrode is in HOMO of 4.7~4.8 eV. Therefore, the Au nanoparticles (AuNP) can be served as a good hole injection layer (HIL), or the HOMO energy level character of ITO with the use of the Au nanoparticles (AuNP) can be also modified.

The organic semiconductor used as the active layer of thin film transistor have widely been widely studied in recent years. Since the organic film of organic thin film transistor (OTFT) is fabricated on the dielectric layer, the performance of OTFT strongly depends on the semiconductor/dielectric interface due to the physical and chanical interactions between the organic layer and the dielectric layer. In this paper, Poly（3-hexylthiophene）（P3HT）was used as an active layer of OTFT and the dielectric surface of SiO2 gate were treated by the process of normal wet-cleaning、O2-plasma、hexamethyldisilazane (HMDS) and octadecyltrichlorosilane (OTS). The purpose of this work is to show that the performance canbe improved with different treatments of dielectric/polymer interface. By using the advantages of polymer dissolved in the organic solvent, the polymer solution can be ink-jet printed with ink-jet technique to fabricate the semiconductor layer of OTFT and to reach the purpose of low-cost and mass-production. By using direct ink-jet printing of solution process, it can provide a new route to fabricate OTFT devices. The experimental result show that the surface treatment of SiO2 with OTS can be allowed to enhance the mobility of the carrier. The surface potential changed by using self-assembled monolayer like OTS technique can lead to hydrophobic state so that the mobility is improved. The highest mobility obtained from OTS-treated sample is nearly 2.026×10-2cm2/Vs. The semiconductor layer of thin film transistor fabricated by ink-jet printing polymer solution process has already been succeeded in this laboratory at present. The measurent of mobility obtained from ink-jet printed sample can achieve 3.892×10-3cm2/Vs. However, it is unsatisfactory compared with spin-coating devices. If there experimented in ink-jet printing process can further be modified, the device performances by also be promted.

The flexible surface acoustic wave (SAW) device is a promising product for the expanded application of SAW device. Over the past few years, a very few attempts have been made it on the flexible substrate. The purpose of this study is to propose an innovated process for fabricating the flexible SAW devices by sol-gel technology and fully ink jet technology. The ZnO solution is prepared by sol-gel technology. We design inter digital transducer (IDT) pattern and deposits ZnO solution on the flexible polyimide plastic (PI) substrate by fully ink jet process. Next, the frequency of SAW device can be measured by the function generator and spectrum analyzer. Here, 7.2MHz is the maximum gain of this device, it will be observed as the SAW center operating frequency. Through the comparison between the predicted value and experimental center frequency, the experimental center frequencies agree with the predicted value. The analysis of surface acoustic wave propagation characteristics is processed by the Finite Element Method (FEM) in future. Finally, the numerical model will be built for optimization.

Recently, Thin Film Transistors (TFTs) have been studied widely because of potential applications in low cost, low-temperature process and flexible displays. They can be fabricated by easy processes based on solution methods. But the mobility of organic TFTs is lower and the threshold voltage is higher than amorphous Si TFTs. In our study, first of all, in order to obtain a high performance Organic TFT, we attempt to discover the best blending proportion of the photosensitive agent ADC to PVA for fabricating organic polymer dielectrics of low leakage current. Then we use this organic insulating layer as the transistor gate insulator layer of double gate thin film transistor devices. The active layer formed the second channel by the second gate would improve the device performance. Finally, we use this device to create inverter circuit. It is found that the threshold voltage have to change as the top gate voltage. That affects our input-output conversion curve of inverters. Second, we prepare the high-k nanocomposite dielectrics for OTFTs by doping TiO2 nanoparticles into polyimide and poly(4-vinylphenol), respectively. To obtain a homogenous organic–inorganic composite film, well-dispersed TiO2 nanoparticles in polyimide solution are important; therefore, several dispersants were assessed on the basis of the measurement of the rheological behavior of slurries. An approximately 400-nm-thick nanocomposite film with homogeneous distribution of TiO2 nanoparticles in polyimide and low roughness is obtained after curing at 200 oC, resulting in a low leakage current density of the nanocomposite film, when less than 2 vol% TiO2 nanoparticles are well dispersed in polyimide slurry. The dielectric constant of the organic–inorganic nanocomposite increases with increasing TiO2 content in polyimide, being situated in the range between 4 and 5 In order to enhance the dielectric constant of nanocomposites and great dispersion for inkjet printing, the polymer PVP and pearl-milling are employed instead of the PI matrix and ball-mill. Then we studied the parameters of ink-jet printing, including voltage, frequency and waveform. We successfully print dielectrics patterns for accomplishing the purpose of directly-patternable. The pentacene-TFT based on the printed nanocomposite dielectrics, which demonstrate high performance with increasing in mobility and reducing threshold voltage. It is observed that a better surface benefits the pentacene growth by Raman spectroscopy. Further, in order to enhance the channel mobility and satisfy with the requirement of low-cost fabrication, we first prepare a low-cost, mask-free, reduced material wastage, deposited technology using transparent, directly printable, air-stable semiconductor slurries and dielectric solutions. We demonstrate an inkjet-printing deposition for fabricating printable transistors with ZnO nanoparticles as the active channel and poly(4-vinylphenol) (PVP) matrix as the gate dielectric, respectively. After annealing at 200 oC, the inkjet-printed ZnO-TFTs exhibit the carrier mobility of 0.69 cm2/Vs, SS of 29 V/decade, and the threshold voltage of 25.5 V. Consequently, a stable and non-precipitated metal oxide ink with appropriate doping was prepared for the fabrication of an all-inkjet-printed transistor by inkjet printing. Transparent materials including dielectric PVP and conductive CNT were employed into the fabrication of our inkjet printing process. The experimental all-printed TFT was annealed at 180 oC and demonstrated a threshold voltage and mobility, and SS are -5 V, 0.194 cm2/Vs, and 20 V/decade initially. In our investigations, we attempt to obtain a high performance and low-cost TFT via preparing materials, designing device structure, and using inkjet printing technology. The soluble direct-printing process is a powerful tool for material research and implies that the printable materials and the printing technology enable the use of all-printed low-cost flexible displays and other transparent electronic applications.

As the increasing challenge of global competition, adopting new technology to introduce new produce of service into market becomes a source of competitive advantage. Digital ink-jet printing technology is an emerging technology in textile industry. The factors affecting the adoption of the digital ink-jet printing technology for enterprises in Taiwan remain unknown, so this study investigates the possible affecting factors based on the following dimensions: business environment, perceived characteristics of innovations and organizational characteristics. Furthermore, this study analyzes the factors which might affect the adoption willingness for enterprises who have not adopted the technology yet. The sample is chosen from enterprises in printing dyeing and finishing industry. The results reveal that “top manager support” and “organizational structure” are influential factors. Especially, the former has greatest influence. Moreover, “compatibility” and “industrial competition” are key factors affecting the adoption willingness of enterprises for the digital ink-jet printing technology in the future.

This study designs and fabricates an split ring resonator with the properties of metamaterials by the fully ink-jet printing technology. The pattern made of nano silver is printed on the flexible polyimide (PI) substrate. S-parameters of this resonator are obtained from the vector network analyzer. The frequency band of the split ring resonator responses in 5.5-6 GHz. It can be converted to obtain the permittivity and magnetic permeability. The fully ink-jet printing technology proposed in this study is robust and cheaper than the MEMS process. Through this fabricated process, the fabrication of metamaterials will become robust and faster. In addition, we expect that this fabricated method can be expanded to the most of manufactured process of film devices, such as SAW devices, transparency film, and metamaterials.
