Abstract

This paper reports our study on surface area of emeraldine phase polyaniline prepared from different concentrations of aniline. The polyaniline was prepared using oxidative polymerization in room temperature. Fourier transform infrared spectrometer and X-ray diffractometer were used to confirm the formation of the conductive phase of polyaniline. The Brunauer-Emmett-Teller surface area measurement was conducted using surface area analyser. The results showed that a high surface area polyaniline was obtained at a relatively low concentration of aniline with the highest BET value of 33.44 m2/g.
