Electrochemical tailoring of fibrous polyaniline and electroless decoration with gold and platinum nanoparticles

摘要

Presented in this work is a facile and quick electrochemical method to control the morphology of thick PANi films, without the use of templates. By stepping the polymerisation potential from high voltages to a lower (or series of lower) voltage(s), the morphology of the polymer was successfully controlled and fibrous structures, unique to each potential step, were achieved. In addition, the resultant films were tested electrochemically for its viability as an electrode material for flexible batteries and supercapacitors. Furthermore, the PANi film was decorated with gold and platinum nanoparticles via an electroless deposition process for possible electrocatalytic applications, whereby the oxidation of hydrazine at the composite was investigated.
