摘要: Bio-inspired chemical approach has been developed for the surface modification and electrophoretic deposition of manganese dioxide zirconia nanoparticles, prepared by precipitation methods. Caffeic acid, trans-cinnamic p-coumaric 2,4-dihydroxycinnamic acid were investigated nanoparticles. The influence structure organic molecules on their adsorption oxide nanoparticles investigated. mechanism caffeic was similar to that natural catecholic amino L-3,4-dihydroxyphenylalanine. use allowed agglomerate-free synthesis, efficient dispersion, charging, co-deposition yield data, coupled with results thermogravimetric analysis, X-ray diffraction Fourier transform infrared spectroscopy, showed chemistry, rather than crystal structure, determined behavior. Electron microscopy energy dispersive spectroscopy investigations formation nanostructured films composites. deposit composition can be varied.
