摘要: Summary: Benzoyl peroxide is used as an oxidizing agent for the first time in synthesis of conducting polypyrrole. Synthesis polypyrrole commonly performed by chemical oxidative polymerization using water-soluble agents. In this work, was prepared organic solvent-soluble benzoyl presence p-toluenesulfonic acid (p-TSA) and sodium lauryl sulfate (SLS) surfactant via inverted-emulsion-polymerization technique. During polymerization, SLS converted to dodecyl hydrogensulfate (DHS) incorporated on along with p-TSA dopant, indicating acting emulsifier well dopant. The influence conditions such duration reaction, temperature, concentration reactants, etc., properties investigated determine optimum salt. Polypyrrole obtained a reaction 1 h high yield (154 wt.-% respect pyrrole used) good conductivity (2 S · cm−1). polypyrrole-salt found be nearly same even after seven months storage at ambient temperature (1.7
