Carbon fibers coated with floral MoSe2 are applied to high-performance electromagnetic absorbing materials

Abstract

Studied the microwave absorption performance of carbon fiber, mixed carbon fiber/MoSe2 (CM) bilayer composite materials in the range of 2–18 GHz. The flower-shaped layer and core-shell double-layer interface of MoSe2 work together to improve electromagnetic wave absorption, providing a new approach for designing lightweight, broadband, and strong absorption-absorbing materials. To address the drawbacks of the high conductivity of pure carbon fibers, transition metal sulfides were introduced promptly, and the CM core-shell materials with flower-shaped outer shell structures were prepared. An in-depth analysis of the working mechanism of CM absorbing materials and the influence of the interface between carbon fibers and MoSe2 on the absorbing performance has been conducted, providing a favorable experimental basis for the application of fiber membranes in absorbing materials.
