▎ 摘　　要

NOVELTY - Method for preparing polydimethylsiloxane (PDMS) sponge-based strain sensor material, involves (a) preparing sugar cubes with white granulated sugar and soft white sugar as raw materials, (b) preparing PDMS sponge with sugar cube as sacrificial template, (c) attaching a graphene oxide to the surface of PDMS sponge and reducing to prepare reduced graphene oxide (rGO)/PDMS sponge, and (d) coating silver nanowires onto the surface of the rGO/PDMS sponge to prepare the silver nanowires rGO/PDMS sponge strain sensor material. USE - The method is used for preparing polydimethylsiloxane sponge-based strain sensor material (claimed), which is used as flexible electronic materials. ADVANTAGE - The preparation method is carried out in a simple manner and easy to operate. The strain sensor material has an excellent electrical conductivity, changes the resistance during compression strain, and has excellent compression cycle stability.
