▎ 摘　　要

NOVELTY - High-performance terahertz absorption composite fabric comprises a flexible fabric base layer and a conductive coating. The flexible fabric base layer is aramid fiber fabric or basalt fiber fabric. The conductive coating is a graphene layer assisted by silk fibroin and a silane coupling agent. The fabric substrate and the conductive coating are connected to each other by hydrogen bonding through the chitosan connecting layer. USE - Used as high-performance terahertz absorption composite fabric. ADVANTAGE - The method has rapid large-scale preparation, low cost, simple operation, and environmentally friendly. The high-performance terahertz absorbing composite fabric has excellent wave-absorbing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a high performance terahertz absorption composite fabric comprising soaking the pretreated fiber fabric in the chitosan solution, drying, transferring to the graphene dispersion solution for soaking treatment and drying to obtain a high-performance terahertz absorption composite fabric, where the fiber fabric is aramid fiber fabric or basalt fiber fabric, and the graphene dispersion liquid is obtained by dispersing graphene, silane coupling agent and silk fibroin in water.
