摘要: Abstract In this study styrenesulfonate of polyaniline/acrylic copolymers were synthesized via free radical polymerization through in dispersed medium. The resulting materials applied onto glass-ITO slides using the air-brushing technique to obtain PAni based thin films. Analyses by scanning electron microscopy TEM mode (STEM) indicated that depending on acrylic monomer combination (methyl methacrylate, methacrylic acid or butyl acrylate) adhesion substrate was better than polyaniline (PAni–SSA) homopolymer. effect monomers electrical properties determined electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Results copolymer could be enhanced varying glass transition temperature. From these findings it concluded inclusion acrylate critical condition improve properties.
