Опубликована: Окт. 30, 2024

Abstract The past decade has witnessed remarkable progress in high‐performance Triboelectric nanogenerators (TENG) with the design and synthesis of functional dielectric materials, exploration novel dynamic charge transport mechanisms, innovative architecture, making it one most crucial technologies for energy harvesting. High output density is fundamental TENG to expand its application scope accelerate industrialization; depends on equilibrium generation, trapping, de‐trapping, migration within core components. Here, this review classifies summarizes approaches enhance collection layers. milestone high reviewed based material selection mechanisms. state‐of‐the‐art principles techniques generating suppressing decay are discussed highlighted detail, distinct advanced materials preparation, effective excitation strategy emphatically introduced. Lastly, bottleneck future research priorities boosting summarized. A summary these cutting‐edge developments intends provide readers a deep understanding high‐output TENG.

The sensitivity of triboelectric nanogenerators (TENGs) to the surface charge density highlights significance materials and their modifications. Efforts have been directed toward developing effective strategies for increasing density, expanding potential applications TENGs. This study proposes use irradiation technology grafting modify electron-donating capability poly(ether sulfone) (PES), thereby affording a dual benefit enhancing inducing shift in position PES from negative positive within series. TENG based on grafted has resulted significant 3-fold increase compared that pristine PES, reaching 263 μC m–2. can be further increased 502 m–2 through pumping. Notably, presents advantages over chemical methods, particularly terms sustainability environmental friendliness. innovative approach shows great advancing domain
