一种柔性石墨烯基压阻传感器及其制备方法
摘要：
本发明公开了一种柔性石墨烯基压阻传感器，包括柔性聚合物基底层、石墨烯‑聚合物复合层、金属电极和聚合物保护层，所述石墨烯‑聚合物复合层置于柔性聚合物基底层和保护层之间，所述金属电极连接在石墨烯‑聚合物复合层顶面的两端；所述石墨烯‑聚合物复合层包括两层，下层为石墨烯扩散于经有机溶剂溶胀的柔性聚合物基底层而形成的石墨烯‑聚合物复合层上层；上层为涂覆聚合物保护层时聚合物渗透填塞石墨烯多孔网状结构薄膜中的孔隙而形成的石墨烯‑聚合物复合层下层。本发明的柔性石墨烯基压阻传感器，柔韧性好、量程大、灵敏度高、压阻重复性好且能耐久使用。
摘要（英）：

The invention discloses a flexible graphene-based piezoresistive sensor. The sensor comprises a flexible polymer substrate layer, a graphene-polymer composite layer, a metal electrode and a polymer protection layer. The graphene-polymer composite layer is arranged between the flexible polymer substrate layer and the polymer protection layer, the metal electrode is connected with the two ends of the top surface of the graphene-polymer composite layer; the graphene-polymer composite layer comprises two layers, the lower layer is an upper layer of the graphene-polymer composite layer formed by diffusing the graphene to the flexible polymer substrate layer swollen by employing an organic solvent, and the upper layer is a lower layer of the graphene-polymer composite layer formed by employing the polymer to permeate and fill pores in a graphene porous mesh structure film when the polymer protection layer is coated. The flexible graphene-based piezoresistive sensor is good in flexibility, large in range, high in sensitivity, good in piezoresistance repeatability and durable for use.
