Synthesis and characterization of a novel conducting graft copolymer
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 H-1- 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.
