Preparation of Conductive Polyaniline Composite Film

Conductive composite material of polyaniline (PAn)/PMMA was synthesized by in-situ chemical oxidative ploymerization of aniline in PMMA solution by using ammonium persulfate as oxidative agent and dodecylbenzene sulfonic acid as dopant. The soluble conductive compositive film was made through the evaporation of solvent.The electrical conductivity of the compositive film reached up to 10 -2 s/cm measured by standard four-probe method. The conditions of synthesis were discussed,and a proper polymerization condition was obtained ,and the stability of the film was discussed as well. The structure and component of the film were characterized by IR and elemental analysis.
