▎ 摘  要

NOVELTY - A graphene-ferrite composite aerogel absorbing material comprises iron-metal organic framework material, graphene oxide aqueous solution and pyrrole. USE - Graphene-ferrite composite aerogel absorbing material for microwave absorption and sensing applications. ADVANTAGE - The composite aerogel absorbing material has high metal organic framework content, and can be prepared quickly by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-ferrite composite aerogel absorbing material, which involves mixing iron chloride hexahydrate and deionized water, stirring until the solution is clear, mixing fumaric acid powder and deionized water, heating in a water bath, stirring until the solution is clear, mixing two solutions, hydrothermally reacting in a polytetrafluoroethylene reactor, washing with ethanol and deionized water, adding graphene oxide powder to deionized water, ultrasonically treating to obtain a brown-yellow graphene oxide aqueous solution, adding 2-50 mg iron-metal organic framework to 1 ml deionized water for 30 minutes, mixing with the graphene oxide aqueous solution and pyrrole, reacting for 8 hours at 95degrees Celsius, aging for 24-72 hours at -20degrees Celsius to -80degrees Celsius, drying, placing in a tube furnace, heating at rate of 1-5degrees Celsius/minute to 600-900degrees Celsius for 1-3 hours, and reducing the temperature.
