Material functionalization of triboelectric nanogenerators (TENG) plays an important role in TENG's electric performance for sustainable energy harvesting. In this work, a method for improving polydimethylsiloxane (PDMS) composites triboelectric performance has been proposed, via filling high dielectric constant liquid (instead of solids) into PDMS matrix. The improvement is attributed to the high dielectric constant liquid in PDMS matrix that reduced the effective thickness of PDMS and increased the dielectric constant of PDMS composite synchronously. At 50% filling ratio (PDMS‐HD50), the triboelectric performance exhibits an enhancement of 4.5‐fold in output voltage and 3.9‐fold in output current as compared to pure PDMS. The results, besides higher transparency, are superior to the results from traditional solid dielectric constant doping materials like BaTiO3 nanoparticle in PDMS. This work has proved potentials of dielectric liquid filling materials in fabricating TENGs and could be a guidance for exploring new liquid filling materials.

摩擦纳米性能增强的液体填充聚二甲基硅氧烷复合材料
摩擦电纳米发电机(TENG)的材料功能化在TENG的电性能中发挥着重要作用,以实现可持续的能量收集。在这项工作中,已经提出了一种通过将高介电常数液体(而不是固体)填充到PDMS基体中来改善聚二甲基硅氧烷(PDMS)复合材料摩擦电性能的方法。改善归因于PDMS基质中的高介电常数液体,从而降低了PDMS的有效厚度并同步增加了PDMS复合材料的介电常数。与纯PDMS相比,在填充率为50%(PDMS-HD50)时,摩擦电性能显示出输出电压提高了4.5倍,输出电流提高了3.9倍。结果,除了更高的透明度之外,PDMS中的3纳米颗粒。这项工作已经证明了介电液体填充材料在制造TENG中的潜力,并且可以为探索新型液体填充材料提供指导。
