| Summary: | Polyaniline powder was prepared by chemically synthesized of aniline monomer in dopant hydrochloric acid solution. The ammonium persulphate solution which was acted as oxidant was added in slowly in the reaction mixture by using magnetic stirrer at room temperature. The reaction took placed for 2h to complete the reaction. After 24h left, the dark green mixture was filtered and washed thoroughly with perchloric acid and disttiled water. The resulting polymer then was dried under vacuum at 80 °C for 4h. The powder then was characterized by FTIR, TGA, DSC and FESEM. Otherwise, the powder was dissolved in dimethyl sulfoxide and mixed with cellulose triacetate solution in dicholoromethane for making composite film. The film was also been characterized and its electrical conductivity was measured by using impedance spectroscopy. |
