▎ 摘　　要

NOVELTY - Cucurbit/oxidation graphene magnetic complex material comprises 1-20 %mass cucurbituril, 1-30 %mass graphene oxide and 50-80 %mass iron oxide nanoparticle. The magnetic complex material is used by mixing cucurbituril, graphene oxide and iron oxide nanoparticle, stirring the mixture, uniformly dispersing the mixture and crushing the dispersed mixture to particle having diameter of 10-100 nm. USE - The complex material is useful for forming cucurbituril dispersed graphene oxide surface (claimed). ADVANTAGE - The complex material is prepared simply and cost-effectively, and has excellent absorbability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the above-mentioned cucurbit/oxidation graphene magnetic complex material.
