▎ 摘　　要

NOVELTY - Metal-organic framework (MOF)-derived composition microwave absorber comprises a porous nano-frame structure including carbon-containing (copper/cuprous oxide) Cu/Cu2O nanoframes and reduced graphene oxide (RGO), where the carbon-containing Cu/Cu2O nanoframe is uniformly loaded on the RGO, where the content of RGO with pyrolysis of carbon is 20-60%, and content of Cu/Cu2O is 40-80%. USE - Used as metal-organic framework-derived composition microwave absorber. ADVANTAGE - The microwave absorber solves the defects that the microwave absorbent has unsatisfactory absorption performance; has large mass and narrow absorption band, porous frame structure, has lighter weight, excellent absorption performance and simple process; and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the MOF-derived composition microwave absorber, comprising (i) preparing a suspended GO solution, collecting by centrifugation, repeatedly washing in water, vacuum-drying, and then dispersing into a methanol solution; (ii) adding methanol solution of 1,3,5-benzenetricarboxylic acid to a solution of copper nitrate pentahydrate and PVP in methanol, magnetically stirring; (iii) magnetically stirring, adding the mixed solution of step (ii) to the GO prepared in step (i), dispersing the methanol solution, completely reacting and centrifuging, then repeatedly washing in methanol and vacuum-drying; (iv) drying the product in the step (iii) and placing in a tube furnace, pyrolyzing at a high temperature; and (v) cooling to room temperature, and collecting the reaction product.
