▎ 摘　　要

NOVELTY - A layered core-shell structured composite absorber comprises hollow zinc ferrite-manganese dioxide-graphene in a mass ratio of 1:(0.92-1.08):(0.60-0.71). USE - Layered core-shell structured composite absorber used as wave absorbing material. ADVANTAGE - The composite absorber has improved the impedance matching property and enhanced wave-absorbing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of layered core-shell structured composite absorber, which involves using ferric chloride hexahydrate, zinc chloride, polyethylene glycol, potassium permanganate and graphene oxide.
