▎ 摘　　要

NOVELTY - Preparing carbon nano tube/polydopamine-reducing graphene oxide/three-dimensional interconnected porous silicon rubber composite material comprises (i) adding graphene oxide into buffer solution, performing ultrasonic treating for one time, then adding polydopamine into the buffer solution, performing secondary ultrasonic treating, reacting completely to obtain poly-dopamine-reducing graphene oxide solution, (ii) adding sacrificial template, carbon nano tube, silicon rubber and curing agent and curing, then completely removing the sacrificial template in the deionized water to obtain the carbon nano tube/silicon rubber three-dimensional interconnected porous substrate, (iii) soaking the carbon nano tube/silicon rubber three-dimensional interconnected porous substrate obtained in step (ii) in the poly-dopamine-reducing graphene oxide solution obtained in step (i) to adsorb, obtaining the composite material. USE - The method is useful for preparing carbon nano tube/polydopamine-reducing graphene oxide/three-dimensional interconnected porous silicon rubber composite material. ADVANTAGE - The material has improved the stability and sensitivity of sensing signal, and stress response sensitivity of the sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for carbon nano tube/polydopamine-reducing graphene oxide/three-dimensional interconnected porous silicon rubber composite material, prepared by above method.
