Preparation of and characterization of conductive Polyaniline (butyl acrylate-vinyl acetate)copolymer composite

In this work, first, copolymer of butyl acrylate/vinyl acetate (ButAc-co- VAC) was prepared by emulsion polymerization in aqueous medium. In the second step, aniline was polymerized in the copolymer matrix by chemical oxidation polymerization. Polymerization of aniline was carried out in the presece of p-toluene sulfonic acid (PTSA) as do pant. Ammonium per sulfate was used as an initiator. Purified composite material of Polyaniline/ (BuA-VAc) was dissolved in dichlorometane by using mechanical mixer. The films was prepared by casting method. The four-point conductivity measurements showd that the blend conductivity is 2.8 S. cm−1. Cyclic voltammograms (CV) revealed that the blend materials are electroactive. It was shown that the electrical activity of polyaniline was transfered successfully to the blend. Amount of conductivity compared with various do pant ions. The mechanical properties of the films indicated that the blend could be considered as an elastomer.
