摘要：
Emeraldin salt of polyaniline was synthesized by chemical oxidative polymerization method; this salt is soluble in common organic solvents. The obtained results are discussed with reference to lactic acid doped polyaniline. It has been observed that acrylic acid doped polyaniline is comparatively more soluble than polyaniline doped with lactic acid in common organic solvent such as m-cresol, NMP (N-methyl pyrrolidinone), DMSO, DMF, etc. The acrylic acid doped polymer prepared using lactic acid is comparatively more soluble in m-cresol and NMP than the polyaniline without acrylic acid. UV-Visible spectra for acrylic acid doped polyaniline reveals the coil conformation at higher wavelength along with sharp peak. This indicates that the conductivity of acrylic acid doped polyaniline is higher than that of polyaniline without acrylic acid. A broad and intense band at 3400-3300 cm(-1) (N-H stretching) and 1120-1225 cm(-1) accounts for higher degree of doping and protonation of amine and imine N-atom. These results are well supported by the conductivity measurement - the conductivity of acrylic acid doped polyaniline is higher than in case of polyan.line without acrylic acid.
