A Study of Multiferroic BiFeO₃/Epoxy Resin Composite as Potential Coating Materials for Microwave Absorption

Abstract:

A single layer of BiFeO₃(BFO)/epoxy resin composite with thickness of 3 mm was fabricated by polymerized 70 wt% of sintered BFO as fillers and 30 wt% of epoxy resin polymer as matrix. The electromagnetic and the microwave absorption properties of BFO/epoxy resin composite were reported. The reflection loss (RL) of the same composite sample was measured by two different techniques of measurement, S_11aparameter (without metal backed reflector) and S_11bparameter (with metal backed reflector) in the range of 8-18 GHz using a network analyzer. Minimum RL (RL_min) from S_11bparameter for BFO/epoxy resin composite with metal backed is lower than the RL_min from S_11acomposite without metal backed reflector. In details, the results showed BFO/epoxy resin composite with metal backed can achieve a strong absorption with RL_minof -40.5 dB over a 1.31 GHz bandwidth.
