A New Form of Polyaniline: Polyaniline Whiskers Prepared in a Bio-Surfactant Reaction Field


Polymerization of aniline in lecithin solution was carried out to prepare polyaniline (PANI)/lecithin composite. Lecithin in the water forms micelles as a surfactant and lamellar liquid crystal. Chemical structure of the composite was characterized with the IR spectra and the optical properties were examined with the UV-vis spectroscopy measurements. Electrical conductivity of the composite increased with increase of lecithin ratio in the component. Thermal properties were examined with thermogravimetric analysis (TG). Scanning electron microscopy (SEM) observation of the composite revealed surface structure of whisker-like form.
