Electrophoretic deposition behavior of ZnO nanoparticles and their properties on conductive fabrics

Abstract

Uniform coating of ZnO nanoparticles on copper coated-polyester fabric was obtained by electrophoretic deposition (EPD). Deposition rate on the fabrics and plates were examined using a kinetic equation. Fabric gives more deposit weight than flat substrate due to rough surface or high surface area. The morphologies and structure of the deposited ZnO layers showed uniform deposition without preferred orientation on both substrates, but a higher deposition rate results in cracks on the surface after drying. The results by PL, UV transmission, and Raman presents slight decrease of bandgap and the shift of Raman peak due to smaller particle size in the as-deposit ZnO films.
