Abstract
Abstract: Microwave-absorbing materials have received numerous attentions in terms of their key roles in the fields of stealth technology and controlling electromagnetic radiation pollution. In this paper, we aim to develop one-dimensional CoFe2O4-TiO2 mixed metal oxide nanocomposite via combination of sol-gel method and electrospinning technique. and investigate its microwave absorbing capability. The phase evolution from precursor fiber to final product and corresponding micromorphology are characterized, and microwave absorption performance for different CoFe2O4-TiO2 composite fibers are investigated with a vector network analyzer in 2-18 GHz. The prepared CoFe2O4-TiO2 mixed metal oxide composite fibers exhibit excellent microwave absorbing ability. The low reflection loss can reach -32.8 dB, and the maximum effective bandwidth is up to 6 GHz (12-18 GHz) at the thickness of 4 mm. The results further reveal that the lightweight mixed metal oxide composite fiber is promising for applications in electromagnetic attenuation and other related research fields.
