Wearable triboelectric nanogenerators (TENGs) with high electrical performance have recently prompted great expectations. However, charge diffusion and recombination affect the electric field strength, resulting in a weak electrostatic potential in the displacement region. Current research on film-type dielectric interlayers indicates that charge trapping can prevent charge recombination, although surface charge air breakdown has not been addressed, and becomes a crucial demand in wearable energy applications. In the present study, the surface charge density of poly(vinylidene fluoride) (PVDF) nanofibers is greatly improved by co-electrospraying PDMS-PVDF (PDPV) charge-trapping microbeads; this new approach prolongs the lifetime of surface charges. In particular, the PDPV beads prevent charge recombination, and the interlocking mechanism enhances the tensile property of the PVDF nanofibers. These result in a two-fold increase in the open-circuit voltage and peak power density to 305 V and 124.3 mW m⁻², respectively. The device is successfully employed in portable electronic gadgets. Ag-nanoparticle-grafted styrene-butadiene-styrene (SBS) fiber is used as an electrode because it has favorable stretchability with low resistance and is antibacterial. The addition of TiO₂/multiwalled carbon nanotube to PVDF nanofiber membrane shows excellent electricfield-induced photocatalyst and ultraviolet protection. Our surface-enhanced fully fiber-based TENG is a promising energy harvester for flexible smart garments applications.

具有高电气性能的可穿戴摩擦纳米发电机 (TENG) 最近引起了人们的极大期望。然而，电荷扩散和复合会影响电场强度，导致位移区域的静电势弱。目前对薄膜型介电夹层的研究表明，电荷捕获可以防止电荷复合，尽管表面电荷空气击穿尚未得到解决，并且成为可穿戴能源应用中的关键需求。在本研究中，通过共电喷涂 PDMS-PVDF (PDPV) 电荷捕获微珠，聚偏二氟乙烯 (PVDF) 纳米纤维的表面电荷密度大大提高；这种新方法延长了表面电荷的寿命。特别是，PDPV 珠可防止电荷复合，互锁机制增强了PVDF纳米纤维的拉伸性能。这些导致开路电压和峰值功率密度增加两倍，达到 305 V 和 124.3 mW m^-2，分别。该器件已成功应用于便携式电子产品。Ag-纳米颗粒接枝苯乙烯-丁二烯-苯乙烯 (SBS) 纤维用作电极，因为它具有良好的拉伸性和低电阻并且是抗菌的。_{将TiO 2} /多壁碳纳米管添加到PVDF纳米纤维膜中显示出优异的电场诱导光催化和紫外线防护。我们的表面增强型全纤维 TENG 是一种很有前途的能量收集器，适用于灵活的智能服装应用。
