Nanoscaled Polyaniline Doped with Different Dicarboxylic Acids Based On Template-Free Method

摘要

With an average diameter of 148-285 nm and a conductivity of 2.38E~(-2)- 5.88 E~(-2)S/cm, Nanoscaled polyaniline (PANI) were synthesized based on template-free method in the presence of dicarboxylic acids dopants (e.g., D-tartaric acid, Succinic acid, maleic acid and fumaric acid). Furthermore, the trans-cis isomerization of butenedioic acid plays an important role in the formation of nanostructures from plane-like to nanofibers, and PANI-MA has larger diameter, higher crystal Unity and conductivity than P ANI-FA.
