A review on the polymers with shape memory assisted self-healing properties for triboelectric nanogenerators

Abstract

Triboelectric nanogenerators (TENGs) are an advanced mechanical energy harvesting system that has a wide range of advantages and has great prospects for use in various fields of science and technology. Among the factors that have a significant impact on the performance of TENGs, a special role belongs to the nature of triboelectric polymer materials. Over the past few years, there has been an exponential growth in research on polymers with shape memory assisted self-healing (SMASH) properties for TENGs. This mini review presents the state of the art in SMASH polymers for TENGs and attempts to assess the impact of modern polymer chemistry on the development of advanced materials for TENGs. Particular attention is paid to the relationship between these polymeric materials and the performance of TENGs. Finally, the problems and promising research directions for polymers with SMASH properties for TENGs are outlined.
