【 摘 要 】

Absorbing materials are developed with the concept of "thin, light, wide and strong", and various methods and materials have been attempted to satisfy the demand. In this work, the in situ growth method were conducted to grow reduced graphene (RGO) into carbon fiber (CF) to prepare CF-RGO composites. Moreover, the phase, microstructure and electromagnetic performance of the flexibility and lightweight composites were characterized. Consequently, the XRD and SEM results indicate the RGO is well grown on the surface of CF. The microwave absorption performance of the as-prepared samples were calculated, and the results show that the effective absorption band of the composites move towards low frequency once the RGO were introduced into the CF.
