Synthesis and Properties of Composites of Oligoazomethine with Char

Conjugated aromatic oligo(azomethine) derivatives (oligo-AMs) were prepared by the condensation of terephtaldehyde 4,4'-diformylbiphenyl bis(4-formylphenyl) ether and p-phenylene diacrolein with 1,4-diaminobenzene at room temperature. The structures of the synthesized oligomers were characterized by FTIR, H-1 NMR, TGA-DTG, UV-vis absorption spectra, and elemental analyses. Additionally, in this study, the oligomer composites were obtained using the carbon material (char) derived from the 450 degrees C pyrolysis of waste polyethylene terephthalates. The conductivity measurements of the produced composites were determined at 24-h periods by doping with iodine vapor. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 123:815-823, 2012
