▎ 摘　　要

NOVELTY - Wave-absorbing material based on shape memory alloy dynamic regulation, comprises a stacked shielding layer (100), a first shape memory material (201), a graphene capacitor layer (400), a second shape memory material (202) and a dielectric material (302). A sub-wavelength structure absorbing layer is embedded in the dielectric material. The two ends of the first shape memory material are respectively connected to the shielding layer and the graphene capacitor layer. The two ends of the second shape memory material are respectively connected to the graphene capacitor layer and the sub-wavelength structure absorbing layer. The graphene capacitance layer can regulate the equivalent square resistance of described graphene capacitance layer by applying voltage. The stretching lengths of the first shape memory material and the second shape memory material are controlled by applying voltages to both ends of the first shape memory material and the second shape memory material. USE - The wave-absorbing material based on shape memory alloy dynamic regulation is useful for preparing graphene used in domestic and external research and preparing liquid crystal and ferroelectric material. ADVANTAGE - The wave-absorbing material can flexibly switch the working state, adjust the wave-absorbing frequency band and amplitude in real time, has a simple structure, strong designability, good controllable effect on the incident electromagnetic wave, and can meet the increasingly complex electromagnetic environment requirements. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing a graphene capacitance layer based on a shape memory alloy dynamically regulated wave-absorbing material DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the structure of a wave-absorbing material based on dynamic regulation of shape memory alloys. 201First shape memory material 202Second shape memory material 400Graphene capacitance layer 402Preparing electrolyte layer
