A new strategy based on inverse microemulsions for electrosynthesis of poly (3-methyl-thiophene) films.

Electroactive poly(3-methylthiophene) (PMT) cannot be electrosynthesized on metallic electrodes in non polar solvents such as alcanes because of the l ack of conductivity. In this work; these conductivity problems have been ov ercome by employing an inverse microemulsion medium made of an homogenous 0 .7 M AOT + 1M HClO4 octane-water (88/12 v/v) mixture. Conductive, electroac tive PMT films were obtained on a Pt electrode. This study shows the intere st of using a usually non conducting, non polar predominantly organic mediu m for the electrosynthesis of polymer films.
