Stretchable piezoelectric nanogenerators (PENGs), as well as triboelectric nanogenerators (TENGs), have become the topic of interest of many scientists for sustainable power generation and power supply to flexible electronics. A piezoelectric composite material can be tailored to develop stretchable PENGs. However, the generated output performance in most of the cases is found to be unsatisfactory because of the low performance. On the other hand, use of flexible elastomeric materials for TENG fabrication is very desirable as this kind of mechanically robust elastomeric material could offer a long service life over hundred million of cyclic operations. In this present work, a high-performance stretchable TENG has been developed comprising 100% amorphous commercial rubbers. The active components of the generator have been prepared following the conventional rubber-processing method—solid-state mixing and vulcanization. Furthermore, the incorporation of functional fillers such as conducting carbon black, precipitated silica, and graphene nanoplatelets into the rubber matrix and modification of the surface microstructure of the active rubber component allow us to improve the output performance of the triboelectric generators. Finally, flexible rubber-based TENG for tire application is demonstrated.

多合一商用橡胶制成的坚固的摩擦发电机

可拉伸的压电纳米发电机（PENGs）以及摩擦电纳米发电机（TENGs）已成为许多科学家感兴趣的可持续发电和向柔性电子设备供电的话题。可以定制压电复合材料以开发可拉伸的PENG。然而，由于性能低下，在大多数情况下产生的输出性能不令人满意。另一方面，非常希望将柔性弹性体材料用于TENG制造，因为这种机械强度高的弹性体材料可以在超过一亿次的循环操作中提供较长的使用寿命。在本工作中，已开发出一种高性能可拉伸的TENG，该TENG包含100％无定形商业橡胶。发电机的活性成分是按照常规的橡胶加工方法（固态混合和硫化）制备的。此外，将诸如导电炭黑，沉淀二氧化硅和石墨烯纳米片之类的功能性填料掺入橡胶基体中，以及通过改变活性橡胶组分的表面微观结构，我们可以改善摩擦发电机的输出性能。最后，演示了用于轮胎的柔性橡胶基TENG。石墨烯纳米片和进入橡胶基质的石墨烯纳米颗粒以及活性橡胶组分表面微观结构的改变，使我们能够改善摩擦发电机的输出性能。最后，演示了用于轮胎的柔性橡胶基TENG。石墨烯纳米片和进入橡胶基质的石墨烯纳米颗粒以及活性橡胶组分表面微观结构的改变，使我们能够改善摩擦发电机的输出性能。最后，演示了用于轮胎的柔性橡胶基TENG。
