Electrochemical synthesis of conducting natural rubber nanocomposite films

Abstract

Homogeneous conducting polymer composite films with improved electrical properties are synthesised by electrochemical polymerisation of aniline on natural rubber. The electrochemical polymerisation is carried out by potentiostatic method using an aqueous solution of 0·1M aniline and 1M sulphuric acid as electrolyte in a single compartment electrochemical cell with steel electrode for collecting the polymer composite. The redox behaviour and stability of the film are studied by cyclic voltammetry. The morphological and spectroscopic analysis revealed an effective formation of the composite. The interfacial properties and ac conductivity of the deposited films are studied by impedance spectroscopy.
