Ring-opening graft copolymerization of epoxide with polyaniline: Chemical properties and lithium ionic conductivity of the copolymer
The NaH-promoted deprotonation of leucoemeraldine base polyaniline (LEB) and its subsequent treatment with phenyl glycidyl ether (PGE) caused the ring-opening polymerization of PGE to give a graft copolymer (LEB-g-PGE). LEB-g-PGE was soluble in acetone and chloroform, which were poor solvents for LEB. An LEB-g-PGE/LiBF4 composite film was obtained through the evaporation of a dimethylformamide solution containing LEB-g-PGE and LiBF4; the film showed an electroconductivity of 1.0 X 10(-6) S cm(-1) at 295 K, as determined by complex impedance analysis.
