▎ 摘　　要

NOVELTY - Graphene composites material comprises an aerosol-deposited film of graphene particles and functional material particles, where the graphene particles are stacked to exhibit c-axis orientation, and the functional material particles are subsumed by the graphene particles. USE - The graphene composite material is used as a radio wave absorbing material in the frequency band of 10-300 GHz, for applying to technical fields such as 5G/6G mobile communication, intelligent transportation systems (ITS), and wireless local area network (LAN). The graphene composite material is used as a heat dissipating/heat dissipating material such as a heat dissipating sheet for electronic devices such as smart phones. The graphene composite material is used as an electrode material for batteries such as lithium-ion batteries, lithium-air batteries, dye-sensitized solar cells, and supercapacitors. The graphene composite material is used as a pressure/strain sensor such as a biological monitor (pulse/blood pressure) and a motion sensor. ADVANTAGE - The graphene composites material has improved functionality derived from graphene and high ploss/pin characteristics in 10-40 GHz band, and exhibits gauge factor of 100-200. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the graphene composites material, involving spraying graphene powder and functional material powder onto a substrate according to an aerosol deposition method.
