Microwave Absorption and Electrical Properties of Coated Polyester Fabric with Cobalt Ferrite and Polyaniline

Abstract

Abstract. In this study, the CoFe 2 O 4 -PANI/PET fabric with microwave absorption and electrical properties was successfully prepared by a facile method. Firstly, the PANI in emeraldine base form was prepared by chemical oxidative polymerization. Secondly, the CoFe 2 O 4 nanoparticles and PANI solution were uniformly dispersed in epoxy resin and coated on the PET fabric. Finally, the conductive properties of the coating surface were obtained by doping. The resultant fabric was investigated by FTIR, SEM and TGA to check its chemical structure, surface morphology and thermal stability. The results of this fabric demonstrated efficient microwave absorption performance and broad absorption bandwidth, which indicating its potential application in microwave adsorption fields.
