Chemical, Electrochemical and Plasma Polymerization of Pyrrole-Aniline Copolymers and Their Characterization

Pyrrole-aniline copolymers (poly(Py-co-Ani)) were synthesized using both three chemical, electrochemical and plasma polymerization methods. Comparison of the with methods was investigated. Fourier transform infrared spectroscopy (FT-IR), thermogravymetric analysis (TG-DTA), scanning electron microscopy (SEM) conductivity results confirmed that poly(Py-co-Ani) successfully obtained in all cases some differences according to synthesis It found method enhanced thermal stability copolymer. The first decomposition temperatures chemically, electrochemically polymerized are 210, 190 250 °C, respectively. However, value copolymer (1,97x10-4 S.cm-1) is lower than chemical (4,40x10-4 (3,14x10-4 copolymers. According findings provides nearly same properties Plasma better can be used for preparing pyrrole aniline
