▎ 摘 要
NOVELTY - The utility model relates to the technical field of composite thin film, and claims a composite radiating type absorbing film, the composite radiating type absorbing film comprises a first polytetrafluoroethylene layer, a first graphene layer, a first manganese-zinc ferrite layer, silver nano-particle layer, a second manganese-zinc ferrite layer; a second graphene layer and a second polytetrafluoroethylene layer; the first polytetrafluoroethylene layer, a first graphene layer, a first manganese zinc ferrite layer, a silver nano particle layer, a second manganese zinc ferrite layer; the second graphene layer and the second polytetrafluoroethylene layer are orderly layered; using the best performance of ferrite wave-absorbing material; it has high absorption frequency band, high absorption rate; the matching thickness is thin; according to the rule of electromagnetic wave propagation from low magnetic conductance to high magnetic conductance direction in the medium, using high permeability ferrite to guide electromagnetic wave; by resonance, a lot of radiation energy for absorbing electromagnetic wave; then converting the energy of the electromagnetic wave into heat energy by coupling, absorbing high efficiency.
