EFFECT OF SULFONIC DOPANTS ON CONDUCTIVITY OF CONDUCTIVE PAPER VIA IN-SITU POLYMERIZATION OF PYRROLE
Polypyrrole (PPy)-coated conductive paper was prepared via in-situ polymerization of pyrrole in pulp suspension using ferric chloride as an oxidant. The dopants used were p-toluenesulfonic acid and its sodium salt (PTSA and PTSA-Na), benzenesulfonic acid (BSA), dodecylbenzene sulfonic acid (DBSA), 2-naphthalene sulfonic acid (NSA) and 9,10-anthraquinone-2-sulfonic acid sodium salt (AQSA-Na). The results showed that the species and dose of dopant ions had significant effect on the surface resistivity of conductive paper. As the dopant, PTSA and DBSA were superior to their corresponding sodium salts. NSA bearing a naphthalene ring and AQSA-Na bearing an anthraquinone ring gave the lowest resistivity, as low as 20 .丒cm-2. For most dopants, the lowest surface resistivity could be obtained when the molar ratio of dopant to pyrrole was 1:1. ATR-FTIR, XPS SEM, and AFM were used to reveal the mechanism involved.
