Abstract
Electrostatic potential induced by contact/tribo electrification on the polymer surface is often regarded as a hazard to be avoided, since it is usually the cause of electrical sparks and accidental fires. However, this electrification effect can also be an opportunity for energy harvesting and self-powered sensors through triboelectric nanogenerator (TENG) technology. More and more electrostatic charges on the surface of triboelectric polymers are the first challenge for improving the performance of TENGs and achieving various triboelectric applications. This perspective reviews strategies for increasing the charge density and the fundamental principles and conclusions related to the triboelectric properties of polymers.
