Triboelectric nanogenerators (TENG) are increasingly considered as a promising energy harvesting system due to high output performance from various wasted energy sources. Numerous studies addressing the TENG configuration improve the performance of these devices by optimizing the paired triboelectric materials and structural geometry. Here, poly(1 H,1 H,2 H,2H-perfluorodecyl methacrylate) (PFDMA) fluoropolymer is adopted as a novel negative tribo-material for application to a TENG, as it is at the topmost negative position of the triboelectric series and it is possible to tune the surface roughness under mild conditions. The intrinsic properties are examined and systematic measurements are carried out with the goal of applying the material to a TENG. PFDMA is suitable for application to a TENG, because PFDMA-TENG exhibits a high voltage, current, and power density of 68V, 6.68 μA, and 150 μW, respectively, under a load of 500 MΩ. Moreover, a PFDMA film offers two distinctive advantages making it ideal for application to a TENG: transmittance higher than 98% even with a relatively high surface roughness, and transfer printing on diverse substrates. The results indicate that PFDMA is a novel negative tribo-material candidate for the fabrication of a TENG with superior triboelectric performance by controlling the surface charge density and morphology.

可转移印刷的基于微图案的含氟聚合物摩擦电纳米发生器

由于各种浪费能源的高输出性能，摩擦电纳米发电机（TENG）越来越被认为是一种有前途的能量收集系统。通过优化配对的摩擦电材料和结构几何形状，许多针对TENG配置的研究都改善了这些设备的性能。在这里，聚（1 H，1 H，2 H，2 H-甲基丙烯酸全氟癸酯）（PFDMA）含氟聚合物被采用作为新型的负摩擦材料，应用于TENG，因为它位于摩擦电系列的最高负位置，且在温和的条件下可以调整表面粗糙度。检验其固有特性，并进行系统测量，目的是将材料应用于TENG。PFDMA适用于TENG，因为PFDMA-TENG具有高电压，高电流，在500MΩ的负载下，功率密度分别为68V，6.68μA和150μW。此外，PFDMA薄膜具有两个独特的优势，使其非常适合应用于TENG：即使表面粗糙度较高，透光率仍高于98％，并且可以在各种基材上进行转印。结果表明，通过控制表面电荷密度和形态，PFDMA是一种新型的负摩擦材料候选物，可用于制造具有优异摩擦电性能的TENG。
