摘要：
In situ polymerization of aniline is carried out in the presence of zinc ferrite to synthesize polyaniline/ZnFe2O4 composites (PANI/ZnFe2O4) by chemical oxidation method. The composite has been synthesized with various compositions (10, 20, 30, 40 and 50 wt.%) of zinc ferrite in PANI. From the infrared spectroscopy (FUR) studies on polyaniline/ZnFe2O4 composites, the peak at 1140 cm(-1) is considered to be measure of the degree of electron delocalization. The surface morphology of these composites is studied with scanning electron micrograph (SEM). The ac conductivity and dielectric properties are studied in the frequency range from 10(2) to 10(6) Hz. The results obtained for these composites are of scientific and technological interest. (C) 2012 Elsevier Ltd. All rights reserved.
