Investigation on the Structural and Magnetic Properties of a Polymer Composite: Polyaniline/Cr₂O₃

摘要

In this paper, we have employed a novel method to realize magnetic property from an organic polymer. An antiferromagnetic, inorganic material Cr₂O₃ added with a well promising Polyaniline was synthesized and the effect of Cr₂O₃ and its concentration on the properties of polyaniline was investigated. Cr₂O₃/PANi was synthesized using solution polymerization method (1, 3, 5, 10 and 15Â wt% of Cr₂O₃). Synthesized Cr₂O₃/polyaniline composites were subjected to Fourier Transformed Infrared Spectroscopy, X-ray diffraction, scanning electron microscopy, vibrating sample magnetometry, to investigate its structural and magnetic properties. The room temperature ferromagnetism was achieved in PANi with 1Â wt.% of Cr₂O₃.
