Design and synthesis of graphene-like porous grapefruit peel/Ni0.5Co0.5Fe2O4 composite with high-performance microwave absorption
Source abstract
Abstract
The rapid developments in communication technology and aerospace have prompted the renewal of electromagnetic wave (EMW) materials. Here, we have prepared graphene-like porous grapefruit peel/Ni 0.5Co 0.5Fe 2O 4 composite by in-situ generation. The graphene-like porous structure improves conductive loss and multi-polarization availably. Meanwhile, the addition of Ni 0.5Co 0.5Fe 2O 4 facilitates to introduce the magnetic loss. Moreover, the large number of pores promotes multiple reflections and scattering of EMW, thus improving EMW absorption performance. Through adjusting the carbonization temperature, the sample with extremely thin thicknesses (1.7 mm) achieves wide effective absorption bandwidth (5.14 GHz). It offers a path to the practical application of new absorbing materials with wider absorption bands and thin thickness.
