Surface modification and cathodic electrophoretic deposition of ceramic materials and composites using celestine blue dye

摘要: A new method has been developed for the surface modification of inorganic particles, which allowed their efficient electrostatic dispersion and cathodic electrophoretic deposition (EPD). The approach is based on use cationic celestine blue (CB) dye as a charging dispersing agent. key advantages this are related to its applicability different materials strong adsorption CB surfaces, critical importance particle dispersion. Proof-of-concept studies involved EPD thin films various materials, such TiO2, MnO2, Mn3O4, BaTiO3, halloysite nanotubes, zirconia yttria. results rate measurements, Fourier transform infrared spectroscopy, UV-vis quartz crystal microbalance provided an insight into mechanism adsorption, interactions OH groups catechol ligand metal atoms surface. It was demonstrated that can be used agent nanoparticle synthesis by chemical precipitation methods. feasibility oxide paved way composites using co-dispersant individual components. Thin oxides were investigated electron microscopy X-ray diffraction benefits nanotechnology formation nanostructured MnO2 commercial high area current collectors energy storage in electrochemical supercapacitors. Testing showed fabrication electrodes with capacitance excellent retention at charge–discharge rates. paves other functional advanced applications.
