▎ 摘　　要

NOVELTY - Microwave absorbing material comprises 1-20% of reduced graphene oxide (RGO)/iron oxide nanoparticles as inorganic non-metallic filler, and 80-99% of polyvinylidene fluoride as a polymer matrix. The reduced graphene oxide/ iron oxide nanoparticles are wrapped to form a core-shell structured RGO that has a thickness of 0.37-0.5 nm. The iron oxide nanoparticles are present in the form of a single layer structure, multilayer structure or single crystal structure, and have a polyhedral shape and a particle size of 120-200 nm. USE - Microwave absorbing material. ADVANTAGE - The material can be simply prepared with light weight, increased corrosion resistance, and good absorbing properties, and is easy to use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing microwave absorbing material, comprising mixing RGO/iron oxide nanoparticles and polyvinylidene fluoride.
