Research progress in carbon-based/carbonyl iron composite microwave absorption materials

Abstract

Carbon-based/carbonyl iron composite microwave absorption materials have become a hot topic in recent years because of the combination of their respective advantages and unique physical and chemical characteristic and good absorbing properties. In this paper, the most recent and important research advances in carbon-based/carbonyl iron composite microwave absorption materials were reviewed. Firstly, the recent research of property improving of carbonyl iron itself was introduced. Then, the research achievements of carbon-based/carbonyl iron composite microwave absorption materials were summarized in six major categories, graphene/carbonyl iron microwave absorption materials, carbon nanotubes/carbonyl iron microwave absorption materials, carbon fibre/carbonyl iron microwave absorption materials, carbon black/carbonyl iron microwave absorption materials, graphite/carbonyl iron microwave absorption materials and the other composites were reviewed in detail. Finally, the performance control and lightweight of carbon-based/carbonyl iron composite microwave absorption materials were pointed out, and its development prospect in broadband stealth was prospected.
