主　　题：carbon foam reduced graphene oxide flake-like nickel cobaltate microwave absorbing materials 

摘      要：Carbon-based foams with a three-dimensional structure can serve as a lightweight template for the rational design and control-lable preparation of metal oxide/carbon-based composite microwave absorption *** this study,a flake-like nickel cobaltate/re-duced graphene oxide/melamine-derived carbon foam(FNC/RGO/MDCF)was successfully fabricated through a combination of solvo-thermal treatment and high-temperature *** indicated that RGO was evenly distributed in the MDCF skeleton,providing ef-fective support for the load growth of FNC on its *** S3,the FNC/RGO/MDCF composite prepared by solvothermal method for 16 h,exhibited a minimum reflection loss(RL_(min))of-66.44 dB at a thickness of 2.29 *** the thickness was reduced to 1.50 mm,the optimal effective absorption bandwidth was 3.84 *** of the absorption mechanism of FNC/RGO/MDCF revealed that its excellent absorption performance was primarily attributed to the combined effects of conduction loss,multiple reflection,scattering,in-terface polarization,and dipole polarization.
