Abstract
Polymer-dielectric triboelectric nanogenerators (TENGs) have attracted significant attention as sustainable power sources for self-powered electronics, haptic interfaces, and intelligent sensing systems. Despite remarkable advances in materials and device architectures, the practical performance of polymer-based TENGs remains fundamentally constrained by insufficient dielectric polarization, limited charge-storage capability, and rapid charge dissipation during repetitive operation.
Herein, we present a dielectric polymer composite strategy with tunable polarization for responsive triboelectric applications. The proposed approach exploits molecular and interfacial engineering to regulate orientational and interfacial polarization within dielectric polymer systems. By controlling dipole alignment through polymer structure design and enhancing charge accumulation at heterogeneous interfaces, the effective dielectric constant and surface charge density can be significantly improved. Various responsive dielectric architectures, including fluorinated polymers with tunable dipole density, bilayer dielectric films with enhanced interfacial polarization, and stimuli-responsive dielectric systems, are demonstrated. The engineered dielectric polarization enables dynamic modulation of triboelectric output under external stimuli such as temperature and mechanical deformation. Furthermore, the relationship between dielectric polarization, charge generation, and triboelectric performance is systematically elucidated. These findings provide a fundamental design framework for next-generation dielectric polymer composites and offer new opportunities for high-performance, responsive, and self-powered triboelectric devices for wearable electronics, sensors, and intelligent human–machine interfaces.
