▎ 摘　　要

NOVELTY - A graphene film like-membranous cobalt ferrite wave-absorbing material preparing method involves dissolving cobalt acetoacetate and iron acetoacetate in the glycol to obtain the solution. The resulting solution is loaded on the graphene by organic thermal decomposition and performed heat treatment to obtain the finished product. USE - Method for preparing graphene film like-membranous cobalt ferrite wave-absorbing material that is utilized for processing civil electromagnetic interference and radar stealth (claimed). ADVANTAGE - The method enables preparing the graphene film like-membranous cobalt ferrite wave-absorbing material with better broadband absorption property and high yield in simple and rapid manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene film like-membranous cobalt ferrite wave-absorbing material.
