摘 要: 利用化学气相沉积(chemical vapor deposition,CVD)法在多孔海绵泡沫镍表面生长多层石墨烯,利用湿法刻蚀掉大部分金属镍,通过对镍颗粒的含量和大小进行控制制备一种新型的高导电柔性海绵状石墨烯/镍颗粒混合结构;然后将柔性混合结构转移到预拉伸的高弹体上,随着高弹体的恢复,得到一种周期性皱褶的海绵状可拉伸气敏材料;最后通过制备电极得到可拉伸的气敏传感器。研究实现了可拉伸技术与气敏传感器的结合,得到了可拉伸的海绵状石墨烯/镍颗粒气敏传感器。
关 键 词: 应用物理学;海绵状石墨烯/镍颗粒混合结构;可拉伸气敏传感器;化学气相沉积法

Abstract: Multilayer graphene was grown on the surface of nickel with porous sponge foam by chemical vapor deposition (CVD) method. Most of the metallic 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 was transferred to the pre-stretched elastomer. With the recovery of the elastomer, a foam-like stretchable gas-sensing material with periodic wrinkles was obtained. Finally, a stretchable gas sensor was 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.
Key words: applied physics; foam-like graphene/nickel particle hybrid structure; stretchable gas sensor; chemical vapor deposition (CVD) method
