“…Additional improvements can be expected in reducing the microcracks and optimizing the texture to reach higher Jc values. Although this new, fast and easy variant technique could still be improved, the values obtained for J c are already satisfactory as compared to those obtained with this similar techniques without rolling [22].…”

High critical current density Jc under high magnetic field is required in numerous applications for high temperature superconductor YBa2Cu3O7-δ (Y123). Significant efforts have been made to control sample preparation in view of optimized textures and microstructures. In YBa2Cu3O7-δ superconductor, Jc is limited by grain misalignment and by other defaults like secondary phase (Y211), microcracks... So YBaCuO films were prepared by electrophoretic deposition directly on polycrystalline Ag substrate. Melt textured growth (MTG) in low oxygen partial pressure and cold rolling were performed to YBaCuO samples respectively to improve texture growth of the films and to study deformation effect on the texture. The film obtained by melted growth after rolling has better texture orientation than the film without rolling, and presents higher critical current density.

Electrophoretic deposition (EPD) method has been developed for the deposition of nanostructured MnO 2 films. Small organic molecules, such as 3,4-dihydroxybenzoic acid (DHB), 3,4-dihydroxyphenylacetic acid (DHP), 3,4-dihydroxyhydrocinnamic acid (DHC), 3,4,5-trihydroxybenzoic acid (THB), hydrocinnamic acid (HCA) and 3-(4-hydroxyphenyl)propionic acid (HPA), were investigated as dispersing agents. It was shown that DHB, DHP, DHC and THB molecules, containing adjacent OH groups bonded to the aromatic rings, provide efficient stabilisation of MnO 2 nanoparticles and enable EPD of MnO 2 films. The results obtained for the DHB, DHP, DHC and THB molecules with different numbers of OH groups and different lengths of hydrocarbon chains were analysed and compared with corresponding experimental data for HCA and HPA without adjacent OH groups. It was demonstrated that the adsorption mechanisms of DHB, DHP, DHC and THB on MnO 2 nanoparticles involved the interaction of adjacent OH groups of organic molecules with Mn ions on the particle surfaces and complexation. The deposits were studied by Fourier transform infrared spectroscopy and scanning electron microscopy. The deposition yield measurements showed that the amount of deposited material can be controlled by variation of dispersant concentration in the solutions and deposition time. The deposition mechanism and kinetics of deposition are discussed. The films prepared by EPD method are promising materials for application in electrochemical supercapacitors.

“…4,[6][7][8] EPD is a simple and low-cost technique, which can be used for the fabrication of large-area coatings. 9 This technique offers important advantages for the deposition of nanostructured films. 10 EPD is achieved via the motion of charged particles in the suspensions toward an electrode and deposit formation under an applied electric field.…”

An electrophoretic deposition (EPD) method has been developed for the deposition of nanostructured zinc oxide (ZnO) and TiO 2 films. It was shown that the stabilization and charging of the nanoparticles in suspensions can be achieved using organic molecules, such as dopamine and alizarin yellow (AY) dye, which were adsorbed on the oxide nanoparticles. Fourier-transform infrared spectroscopy investigations showed that the adsorption mechanism is based on the complexation of metal ions at the surfaces of oxide nanoparticles. Cationic dopamine additive was used for the formation of deposits by cathodic EPD. The adsorption of anionic AY on the oxide nanoparticles resulted in charge reversal and enabled the formation of anodic deposits. The method enabled the codeposition of ZnO and TiO 2 and the formation of composite films. It was shown that the deposition yield and deposit composition can be controlled by the variation of deposition time and suspension composition. The deposits were studied using X-ray diffraction and electron microscopy. The deposition mechanism and kinetics of deposition are discussed.
