摘要：
Low-frequency microwave absorption remains a key issue to plague the attenuation of electromagnetic energy in conventional absorber. In this work, lightweight and flexible composite textiles were fabricated by in situ synthesis method. The microstructure and electromagnetic properties of the composite textiles were studied. The carbonyl iron/reduced graphene oxide/non-woven fabric (NW-RGO-CI) composite textiles possess excellent microwave absorption performance at low frequency range (2.91-5.1 GHz), and the qualified bandwidth of the composites reaches 9.2 GHz, which originates from synergistic effect of electricity and magnetism. The as-fabricated flexible and lightweight composite textiles could serve as potential materials in wearable electromagnetic absorption coatings and devices.
