Preparation of highly conducting and processable polyaniline was carried out in the presence of anionic surfactant AOT (di-2-ethyl hexylsulfosuccinic acid sodium salt) together with hydroxypropylcellulose(HPC) as processable highly conductive polyaniline. The good environmental and electrical stability of PANI seems to be very promising conducting polymer. Several types of acid and dopants can be used to synthesize highly conductive PANI with conductivity as high as 300S/cm. These were achieved by so-called 2-steps method: first PANI in emeraldine salt (ES) form was synthesized and then dedoped into emeraldine base (EB) form; secondly the EB powder was redoped with dopant (CSA, DBSA and etc) and dissolved in m-cresol and cast into film.[1-3] This method is cost and time consuming as compared to our method, where the PANI is prepared in the presence of dopant(AOT) and then "in-situ" secondary doped by direct addition of m-cresol in the PANI solution.[4]
