Abstract Triboelectric nanogenerator (TENG) as an environmental energy recovery and harvesting technology has attracts much attention. However, the improvement of TENG's output performance becomes one core issues. And modification triboelectric materials may be effective approach. Here, two metal–organic framework (MOF) namely TIFSIX‐2‐Cu‐i Cu(Qc) 2 are synthesized, influence different organic ligands on electromechanical conversion TENG is investigated by starting from intrinsic structure MOFs. With polydimethylsiloxane (PDMS)@TIFSIX‐2‐Cu‐I PDMS@Cu(Qc) layer, electrical increases 4.5 times 3 times, respectively. Meanwhile, a double dielectric layer composite proposed to further improve TENG. Accordingly, MOF‐TENG with shows maximum power density 0.12 mW cm −2 , which 6.3 than that original Based designed management circuit, exhibits good supply capability can sustainably small electronics just human mechanical energy. This work proposes new strategy promote development self‐powered or systems.

Liquid Metal-Promoted Supramolecular Interactions Enable Ultrafast Self-Healing Triboelectric Materials with High Performance at Room Temperature

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Апрель 10, 2025

Soft self-healing materials are excellent candidates for wearable devices to power sensors due their compliance, extensibility, and self-restorability. However, combining ultrafast autonomous restorative properties with mechanical capabilities application in self-powered device still poses challenges. Utilizing the high mobility conductivity of liquid metal, this paper incorporates it into polydimethylsiloxane by a supramolecular interfacial assembly strategy prepare triboelectric material ultrahigh stretchability (12000%) remarkable (30 min at ∼25 °C). The dynamic bonds endow universal ability under extreme environments (-20 °C, near infrared, underwater), durability, (100 V 0.81 W/m2). By integrating devices, real-time feedback on human joint movement is enabled. This work offers valuable balance trade-off between shape adaptation self-healing, paving way enhanced applicability sensing applications.
