▎ 摘　　要

NOVELTY - A composite elastomer comprises porous materials and graphene-coated metal nanowires. The graphene-coated metal nanowires are grown on skeleton of porous material. The porous material comprises resilient porous material. USE - Composite elastomer is used for flexible electronic device, sensor, supercapacitor and water treatment (all claimed). ADVANTAGE - The composite elastomer has rebounding and restoring characteristics to original shape within 2 seconds after pressing and releasing, and resistance change rate of less than 10%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite elastomer, which involves dispersing metal salt and graphene oxide in deionized water, adding coating agent and base, further adding reducing agent under stirring to obtain mixed dispersion, adding porous material to mixed dispersion liquid, ultrasonically treating mixture to obtain reaction solution, heating reaction solution at 60-100 degrees C for 30-120 minutes, washing porous material and drying porous material.
