Nghiên cứu polyme hóa anilin bằng phân cực điện hóa

Abstract

PANi can be synthesized by electrochemical techniques in an acid solution on metal electrodes. Tree techniques usually applied are cyclic voltammetry (CV), potentiostatic (PS) and galvanostatic (GS) polarisation, among them GS method has many advantages. Using electric current density J = 7 mA/cm², concentration of aniline monomer 5 up to 30 g/l in H₂SO₄ 1M solution, synthesis of polyaniline was realised continuously during 3 h and 5 h. It has been found that both polymer product conversion and electric current reaction productivity, H_m and H_J respectively, are relatively high. H_J depends strongly on the monomer concentration Journal of Chemistry, T. 42 (1), Tr. 52 - 56, 2004 Full text of this article is in Vietnamese.
