Synthesized of Conductive Polyaniline by Solution Polymerization Technique

Polyanilines (PANIs) have been synthesized by the emulsifier free polymerization process utilized Ammonium Persulphate (APS) as an initiator at room temperature (28 C). The complete reaction of polymerization process was indicated by increasing viscosity from 20 mPa.s to 180 mPa.s. A particle size formation also was observed during the polymerization process. Both indicators occured due to a proceeding progress of polymer molecule chain. Hence, the formation of polymer particle is confirmed. In addition, temperature test indicated that there was an increase in temperature from 28 C in the first 120 minutes to 52 C after 8 hrs progressing time. Evidently, an increment in the temperature was due to an increase of reaction rates. The present of synthesized PANI was then confirmed by their respective FTIR spectrum. It is concluded that PANI has successfully synthesized by the emulsifier free polymerization process. The electrical conductivity value of PANI is driven by protonic acids. This value shown significant increase from 17.5 μS/cm as pure PANI to 3600, 1520 and 920 μS/cm after the addition of photonic acids of HClO4, H2SO4 and HCl.
