Triboelectric nanogenerators (TENGs) have attracted considerable attention owing to their versatile potential to meet the needs of renewable energy sources. TENG materials have both electrical and mechanical excellence, considering the common mechanism of contact electrification. In this study, ladder-like structured poly(1H,1H,2H,2H-nonafluorohexyl-co-2-(3,4-epoxycyclohexyl)ethyltrimethoxy silsesquioxane)s (LPEFSQs) were synthesized as a hard coating material in TENG applications. LPEFSQs contain the UV-curable functional group and halogen elements and can be coated easily on various polymeric films. Such hard coating films of LPEFSQs enhance the electrical and mechanical properties of any polymer substrate. A LPEFSQ-based TENG exhibits superior performance in both aspects than polytetrafluoroethylene, an extreme triboelectric material commonly used as a negative side. In a large-scale demonstration, the open-circuit voltage and short-circuit current outputs reached 1140 V and 23μA, respectively. Therefore, this hard coating material will provide a facile but efficient method to increase the electrical performance of TENGs in harsh mechanical environments.

含氟梯状结构聚倍半硅氧烷的硬涂层薄膜作为高性能摩擦发电机的负摩擦电材料

摩擦纳米发电机(TENGs)因其在满足可再生能源需求方面的多功能潜力而引起了广泛关注。考虑到接触带电的常见机制,TENG 材料兼具电气和机械性能。在这项研究中,梯形结构的聚(1H,1H,2H,2H-九氟己基-co-2-(3,4-环氧环己基)乙基三甲氧基倍半硅氧烷)(LPEFSQs)被合成为 TENG 应用中的硬涂层材料。LPEFSQ 含有紫外线固化官能团和卤素元素,可轻松涂覆在各种聚合物薄膜上。LPEFSQ 的这种硬涂层膜增强了任何聚合物基材的电气和机械性能。基于 LPEFSQ 的 TENG 在这两个方面都表现出优于聚四氟乙烯的性能,一种极端的摩擦电材料,通常用作负极。在一次大规模演示中,开路电压和短路电流输出达到了 1140 V 和23μ一个, 分别。因此,这种硬涂层材料将提供一种简便而有效的方法来提高 TENG 在恶劣机械环境中的电气性能。
