Synthesis and electrochemical properties of poly(2,3-dimethylaniline)/polyaniline composites

In this study, poly(2,3-dimethylaniline)/polyaniline (P(2,3-DMA)/PANI) composite was prepared by in situ polymerization of aniline on the surface of P(2,3-DMA) particles in hydrochloric acid solution. Fourier transform infrared spectra and X-ray diffraction results of the composites indicated that P(2,3-DMA) was successfully modified by PANI. The electrochemical activity and electrical conductivity of the P(2,3-DMA)/PANI composite were discussed by cyclic voltammetry and standard four-probe tests, respectively. The results showed that the conductivity of the composite increased with the increasing aniline concentration, which can expand the potential applications of P(2,3-DMA), such as use in anti-static coatings or electronic devices. The P(2,3-DMA)/PANI composite also showed better solubility and anticorrosive property than PANI. POLYM. COMPOS., 36:1541-1545, 2015. (c) 2014 Society of Plastics Engineers
