▎ 摘  要

NOVELTY - Heat-conducting and wave-absorbing integrated flexible material is claimed. The heat-conducting and wave-absorbing integrated flexible material is prepared by filling heat-conducting and wave-absorbing agent graphene, heat-conducting and wave-absorbing agent polypyrrole and heat-conducting functional filler in the silicone oil base according to certain proportion, and performing solidifying and film-forming process with demolding paper, where mass ratio between graphene, polypyrrole and heat-conducting functional filler is 1:1:10-20. USE - The heat-conducting and wave-absorbing integrated flexible material is useful in the field of electronics, communications, automobiles, medical appliances, household appliance products, aerospace, security monitoring and navigation (all claimed). ADVANTAGE - The heat-conducting and wave-absorbing integrated flexible material has excellent heat-conducting and wave-absorbing performance, and overcomes the problem that the existing separated heat-conducting and wave-absorbing plate e.g. large thickness, high production cost, poor heat-conducting and wave-absorbing performance and complex process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing heat-conducting and wave-absorbing integrated flexible material, comprising (i) weighing graphene, polypyrrole and heat-conducting functional filler according to mass ratio, then dispersing graphene, polypyrrole having planar spiral structure and heat-conducting functional filler in deionized water, ultrasonically dispersing, stirring, freezing and vacuum drying to obtain dry adhesive for future use, and (ii) dispersing the dry adhesive in silicone oil matrix, stirring, and defoaming under vacuum conditions, and then curing to obtain final product.
