▎ 摘　　要

NOVELTY - Terahertz absorbing material comprises three-layer three-dimensional graphene/polydimethylsiloxane composite material, where the former layer of three-dimensional graphene/polydimethylsiloxane composite material. The three-dimensional graphene pore size is 100-120 mu m. The latter layer of the three-dimensional graphene/polydimethylsiloxane composite. The pore size of three-dimensional graphene is 50-70 mu m. USE - Terahertz absorbing material. ADVANTAGE - The terahertz absorbing material has extremely strong broadband terahertz wave absorption characteristics, and average absorption rate of 0.2-1.2 terahertz as high as 93%, extremely thin thickness, thickness control of each layer within 1 mm, and a total thickness of the terahertz absorbing material of 3 mm, excellent flexibility, flexibility, stretchability, and mechanical elasticity, which is much better than existing terahertz absorbing foam materials, and can be prepared in a simple and cost-effective manner.
