Abstract Fluoropolymers, including polytetrafluoroethylene (PTFE, Teflon), polyvinylidene difluoride (PVDF), and fluorine kautschuk materials (FKMs, Viton) are critical polymers for applications ranging from non‐stick coatings, corrosion resistant seals, semiconductor manufacturing, membranes, energy harvesting technologies. However, the synthesis of these fluoropolymers requires use per‐ polyfluorinated alkyl substances (PFAS) known colloquially as “forever chemicals,” such there is a pressing need to develop alternative technologies that can serve end‐use without environmental cost using PFAS. Further, themselves fall under PFAS umbrella. Here, mechanical‐to‐electrical reviewed benchmarked against leading fluoropolymer harvesters. These include nonfluoropolymer piezoelectric polymers, triboelectric nanogenerators (TENGs), ferroelectric elastomers, flexoelectric polymers. A vision towards sustainable, non‐fluoropolymer‐based provided.

Achieving Ultra‐Durability and High Output Performance of Triboelectric Nanogenerators

Advanced Functional Materials, Год журнала: 2023, Номер 34(9)

Опубликована: Ноя. 22, 2023

Abstract With rapid development of the Internet Things (IoTs) era, a variety miniaturized and distributed electronics appear in every corner industrial production daily life. The shortage fossil fuels requires renewable clean energy to replace traditional meet needs smart low‐power devices. Triboelectric nanogenerator (TENG) is new technology for converting high‐entropy mechanical into electric power these However, improving output durability TENG remains considerable challenge practical applications. To solve problems push forward its commercialization process, this paper systematically reviews how improve sliding mode (S‐TENG) from aspects material optimization structural design. Besides, ways are introduced S‐TENG under premise high durability. At last, challenges future research focus field also predicted, which provide guideline ultra‐durability highly efficient harvesting self‐powered sensing applications IoTs.
