摘要：
We report a simple procedure for fabricating flexible, free-standing, and magnetic film of GO/CNT-Fe3O4 composites by using a one-pot co-precipitation in situ growth route. Characterizations including X-ray diffraction, Raman spectroscopy, superconducting quantum interference device magnetometry, scanning electron microscopy and transmission electron microscopy have been carried out to investigate the morphology, crystalline structure and magnetic properties of the composites. The layered structure of the as-prepared composites is porous and superparamagnetic. The GO/CNT-Fe3O4 composites exhibit excellent microwave absorbing properties in the range of 2-18 GHz and are expected to be promising candidates as microwave absorbing materials.
