▎ 摘　　要

NOVELTY - A graphene oxide/barium ferrite absorbing material is prepared by using pure barium nitrate (Ba(NO3)2) and ferric nitrate (Fe(NO3)3) as raw material and citric acid and ethylene glycol as composite complexing agent to form aqueous graphene oxide sol solution, continuously heating and stirring to form gel, and subjecting gel through microwave assisted self-ignition combustion. USE - Preparation of graphene oxide/barium ferrite absorbing material. ADVANTAGE - Preparation process shortens reaction time and avoids high temperature sintering process.
