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, and energy harvesting technologies. However, the synthesis of these fluoropolymers requires the use of per- and polyfluorinated alkyl substances (PFAS) known colloquially as “forever chemicals,” and as such there is a pressing need to develop alternative technologies that can serve the end-use of fluoropolymers without the environmental cost of using PFAS. Further, fluoropolymers themselves fall under the PFAS umbrella. Here, alternative mechanical-to-electrical energy harvesting polymers are reviewed and benchmarked against the leading fluoropolymer energy harvesters. These alternative technologies include nonfluoropolymer piezoelectric polymers, triboelectric nanogenerators (TENGs), ferroelectric elastomers, and flexoelectric polymers. A vision towards sustainable, non-fluoropolymer-based energy harvesting is provided.

用于基于运动的能量收集的含氟聚合物的替代品:压电、摩擦电、铁驻极体和挠曲电的观点



含氟聚合物,包括聚四氟乙烯(PTFE、Teflon)、聚偏二氟乙烯(PVDF)和氟考特舒克材料(FKM、Viton)是不粘涂层、耐腐蚀密封、半导体制造、膜和能量收集技术等应用的关键聚合物。然而,这些含氟聚合物的合成需要使用俗称“永久化学品”的全氟和多氟烷基物质 (PFAS),因此迫切需要开发替代技术,以服务于含氟聚合物的最终用途,而无需使用 PFAS 的环境成本。此外,含氟聚合物本身也属于 PFAS 范畴。在这里,我们对替代的机械-电能收集聚合物进行了审查,并与领先的含氟聚合物能量收集器进行了基准比较。这些替代技术包括非氟聚合物压电聚合物、摩擦电纳米发电机 (TENG)、铁电弹性体和柔性电聚合物。提供了可持续的、基于非氟聚合物的能量收集的愿景。
