Preparation of polyaniline nanofibers via a novel interfacial polymerization method

Polyaniline (PANI) nanofibers were prepared via a novel interfacial polymerization method. In this method, aniline dissolved in xylene that is immiscible to water was directly added into the aqueous solution of the oxidant under stirring. The polymerization was carried out at the interface formed between the organic liquid drops and the water. The morphology, structure and water-dispersity of the samples prepared under different conditions were investigated by the aid of TEM, SEM, FT-IR and UV–vis spectra. The conductivity of the samples was also measured through typical four-probe technique.
