海绵状石墨烯/镍颗粒混合结构可拉伸气敏传感器的制备

Multilayered graphene was grown on the surface of nickel with porous sponge foam by chemical vapor deposition (CVD). Most of the metal nickel was etched by wet etching. A new type of highly conductive flexible sponge Graphene/Nickel Particle hybrid Structure was prepared by controlling the content and size of nickel particles. And then the flexible hybrid structure is transferred to the pre-stretched elastomer. With the recovery of the elastomer, a foam-like stretchable gas-sensing material with periodic wrinkles is obtained. Finally, a stretchable gas sensor is obtained by preparing an electrode. The combination of stretchable technology and gas sensor was realized, and a stretchable foam-like graphene/nickel particle gas sensor was obtained.
