Title: AN ELECTROACTIVE ELASTOMER - POLYANILINE NITRILE RUBBER
Author: TASSI, EL
DEPAOLI, MA
Abstract: An electroactive elastomeric material was prepared by the electrochemical graft copolymerization of aniline with nitrile rubber. The synthesis has been carried out potentiostatically, potentiodynamically or galvanostatically in a non-aqueous medium using a nitrile-rubber-coated working electrode. Infra-red spectra of the products resemble a superposition of nitrile rubber and polyaniline spectra. However, thermogravimetry, differential scanning calorimetry and solubility experiments indicate that the polyaniline chains grow as grafted branches of the nitrile rubber chains. Scanning electron microscopy indicates no phase segregation in accordance with this assumption. Cyclic voltammetry experiments indicate that the new material has the same electroactivity as pure polyaniline.
