Influence of structure of polyacid on synthesis and properties of interpolymer polyaniline complexes

Abstract

Chemical matrix polymerization of aniline was performed in the presence of polyacids with various macromolecule chain flexibility. Aniline polymerization in the presence of flexible chain polyacids leads to the formation of interpolymer complexes of polyaniline (PANI) of double-stranded structure with a high content of localized polarons and, in the presence of rigid chain polyacids, it leads to the formation of complexes with comblike structures with a high content of delocalized polarons. During the synthesis of PANI at a reduced temperature, the induction period increases and the films of the obtained complexes have high conductivity than in the case of synthesis at room temperature. Electrical and spectral properties and surface morphology of the PANI interpolymer complexes were investigated.
