摘要：

4, 4'-Diaminodiphenyl sulphone was polymerized (with lithium/cobalt/lithium-cobalt salts) by chemical oxidation method using potassium perdisulphate. The solubility of the chemically prepared polymer-metal nanocomposite was ascertained and it showed good solubility in DMF, chloroform, trichloroethylene and DMSO. The PDDS-Li/Co/Li-Co nanocomposites were characterized by UV-vis and FTIR spectral studies. Amine and imine vibrations observed at 1593 and 1503 cm(-1) were shifted to lower wave numbers when the polymer-metal composites were formed. A single absorption peak clue to the N-H stretching vibration of the imino groups of polymer-metal nanocomposite is observed around 3459 cm(-1) and it suggests the participation of NH group during polymerization. The X-ray diffraction studies revealed the formation of nano sized (82 nm) crystalline polymer. The conductivity of the PDDS-Li-Co nanocomposite was determined to be 6.26 x 10(-2) S cm(-1). SEM analysis showed mixed granular nature of the polymer-metal nanocomposite. The capacitance (159.04 mu F) of chemically synthesized PDDS-Li-Co nanocomposite is suggested as a potential capacitive material. (C) 2010 Elsevier B.V. All rights reserved.
