Synthesis and enhancing electrical properties of PANI and PPA composites

Polyaniline (PANI) was prepared by chemical method using FeCl3 as oxidizing agent. Emeraldine base (EB) was prepared using 0.1 M ammonia solution, and redoped using HCl, (±)-10-camphorsulfonic acid (CSA) and p-toluenesulfonic acid (PTSA). The electrical conductivity of EB was increased by doping. Polyphenylacetylene (PPA) and its complexes with KI and NaOEt were prepared and their electrical conductivities were studied. FTIR was used for characterizing the structures.
