Synthesis of Nano-Structured Polyaniline by Direct Emulsion Polymerization

A direct emulsion process was performed for the synthesis of an emeraldine salt of polyaniline (PANI) using a novel surfactant, namely cetyl dimethyl ammonium phenyl chloride (CDAPhCl). HCl was used as dopant and potassium persulfate(KPS)was used as an oxidizing agent. Variation of polymer yield was recorded using conventional gravimetric method and resulting polymer salt was analyzed by FTIR. Average particle size and latex morphology was studied using dynamic light scattering (DLS) and scanning electron microscopy (SEM).Furthermore, the influence of the reaction time followed by polymer yield on the conductivity of resulted PANIsalt was investigated. SEM images showed a nanostructured polyaniline and conductivity of the polyaninle film found to be 1.65 S cm-1.
