Abstract:

Poly (2,5-dimethoxyaniline) (P25DMAn) powder and film have been synthesized respectively by chemical and electrochemical methods. These polymers were characterized by elemental analysis, FTIR, UV-VIS spectroscopy, electrical conductivity measurement and cyclic voltammetry. The structure of P25DMAn is closed to that of polyaniline, with monomer units linked through the nitrogen atom and para-positions. P25DMAn can be dissolved in a variety of organic solvents (THF. CH2C12, CHC13, DMSO, DMF, et al.). The polymers exhibite excellent environmental stability, high electrical conductivity and electrochemical activity. The polymers have a attractive application potential as an electrode material.
