Synthesis of Polyaniline by the Microemulsion Method and its Electrochromism Property

The polyaniline was synthesized by the microemulsion method with ammonium persulfate (APS) as an oxidant in functional protonic acid-water-n-butyl alcohol systems. With the conductivity and electrochromism property of the polyaniline as a standard,the influence of the initiator ,dodecyl benzene sulfonic acid (DBSA), reaction temperature and reaction time on the polyaniline property was discussed . The factors influencing the composite film property of polyaniline/ polyvinyl alcohol (PAn/PVA) were preliminarily explored.The results showed that the conductivity of the (PAn/PVA) film synthesized by the microemulsion method raised two orders of magnitude and the electrochromism property is better compared with that synthesized by the conventional emulsion method.
