Synthesis and Characterization of a Novel Conducting Graft Copolymer

Abstract

The electrically conductive graft (g) copolymer, poly(dimethylolpropionic acid –co-adipoyl chloride)-g-poly(aniline) (PDMPAAC-g-PAni) was prepared by the electrochemical polymerization of aniline (Ani) using a precursor polymer, poly[(4-aminophenyl)-dimethylolpropionic amide-co-adipoyl chloride] (PADMPAAC). PADMPAAC was synthesized chemically by reacting PDMPAAC with 1,4-phenylenediamine. The electrochemical properties of graft copolymer are compared with those of PDMPAAC/PAni composites. Synthesis of PDMPAAC and PADMPAAC was characterized using 1 et al. , ( 1997 ). Handbook of Organic Conductive Molecules and Polymers , John Wiley & Sons Inc. : Chichester . [Google Scholar]H-NMR, FT-IR spectroscopy. The electrochemical properties of the novel conducting copolymer were investigated using cyclic voltammetry (CV) and chronoamperometry (CA); thermal properties were investigated using thermogravimetric analysis (TGA). The electric conductivity was measured with four-probe method.
