Synthesis of conducting polymer with green chemistry and its electrochromic properties

Thanks to their interesting optical and electrical properties, conductive polymers are one of the materials to have highest potential utility in technological applications. but theirs usage in practicalapplications are limited due to poor solubility, cannot be easily processed and lack of good mechanical strength and stability. in this work, synthesis of conductive polymer was achieved in environmentally friendly aqueous dispersion of polystyrene sulfonic acid instead of harmful organic solvent (dichloromethane, acetonitrile, chloroform,). thus, a water-insoluble monomer was polymerized in an aqueous medium instead of organic solvents which are harmful to environment and human health. also, conductive polymer obtained in aqueous medium has superior optical and electrical properties than the conductive polymer obtained in the presence of organic solvents. this paper has been shown that other conductive polymers synthesized in hazardous organic solvents can be synthesized in aqueous media with superior optic and electrical properties which is important for the technological application.
