electrical and mechanical properties OF POLYANILINE FILMS——EFFECT OF NEUTRAL SALTS ADDED DURING POLYMERIZATION

Chinese Journal of Polymer Science 1998年第1期16卷 1-8页

作者：万梅香刘丽娟王军 Institute of Chemistry The Chinese Academy of Sciences Beijing 100080 China

The electrical and mechanical properties of polyaniline (PANI) films synthesized by the presence of the selected neutral salts in the polymerization were measured as a function of the properties and the concentration of the selected neutral salts, and the protonation state. It was found that both the electrical and mechanical properties of PANI films were enhanced by adding neutral salts in the polymerization. The adding of the neutral salts in the polymerization resulted in extended conformation of polymer chain and increasing of molecular weight of PANI, which may be the reasons why the electrical and mechanical properties of PANI films were improved by the presence of neutral salts in the polymerization.
