Synthesis and Characterization of Polyaniline Conductive Composite Films

Abstract:

Conductive polyaniline(PANI) was synthesized by chemical oxidative copolymerization , using dodecylbenzene sulfonic acid (DBSA)as doping agent. PANI-DBSA/ABS conductive films were obtained by solution blending method, using chloroform as organic solvents. The products were characterized by means of digital four-point probe meter, FT-IR spectroscopy, thermal gravimetric analysis (TGA) and inverted metallurgical microscope. The results indicate that PANI-DBSA has good solubility because dodecylbenzene sulfonic acid (DBSA) plays a good doping role in polyaniline. Composite films’ electric conductivity improves with the increasing content of PANI and the percolation threshold is about 10wt% when conducting network formed. TGA curves demonstrate that product’s glass transition temperature is much higher than acrylonitrile-butadiene-styrene resin, furthermore, the thermal stability of composite films also improves compared with polyaniline or resin.
