Abstract

Recycling plastic waste into triboelectric nanogenerators (TENGs) presents a sustainable approach to energy harvesting, self-powered sensing, and environmental remediation. This study investigates the recycling of polyvinyl chloride (PVC) pipe waste polymers into nanofibers (NFs) optimized for TENG applications. We focused on optimizing the morphology of recycled PVC polymer to NFs and enhancing their piezoelectric properties by incorporating ZnO nanoparticles (NPs). The optimized PVC/0.5 wt% ZnO NFs were tested with Nylon-6 NFs, and copper (Cu) electrodes. The Nylon-6 NFs exhibited a power density of 726.3 μW cm⁻²—1.13 times higher than Cu and maintained 90% stability after 172 800 cycles, successfully powering various colored LEDs. Additionally, a 3D-designed device was developed to harvest energy from biomechanical movements such as finger tapping, hand tapping, and foot pressing, making it suitable for wearable energy harvesting, automatic switches, and invisible sensors in surveillance systems. This study demonstrates that recycling polymers for TENG devices can effectively address energy, sensor, and environmental challenges.

聚氯乙烯（PVC）管道废弃物回收利用为基于PVC/ZnO纳米纤维的摩擦电纳米发电机

将塑料废物回收到摩擦电纳米发电机（TENGs）中，为能量收集、自供电传感和环境修复提供了一种可持续的方法。本研究探讨了聚氯乙烯（PVC）管道废弃聚合物的回收利用，并将其转化为纳米纤维（NFs）。我们着重于优化回收PVC聚合物的形貌，并通过加入ZnO纳米粒子（NPs）来提高其压电性能。优化后的PVC/0.5 wt% ZnO纳米纳米管在尼龙-6纳米管和铜电极上进行了测试。尼龙-6 NFs的功率密度为726.3 μW cm−2-1.13倍，比Cu高，在172,800次循环后保持90%的稳定性，成功地为各种彩色led供电。此外，一种3d设计的设备被开发出来，可以从生物力学运动（如手指敲击、手敲击和脚按压）中收集能量，使其适用于可穿戴能量收集、自动开关和监控系统中的隐形传感器。这项研究表明，回收聚合物用于TENG设备可以有效地解决能源、传感器和环境方面的挑战。

期刊介绍： Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. The journal aims to publish high quality research related to materials for energy harvesting, conversion, storage, and transport, as well as for creating a cleaner environment. EEM welcomes research work of significant general interest that has a high impact on society-relevant technological advances. The scope of the journal is intentionally broad, recognizing the complexity of issues and challenges related to energy and environmental materials. Therefore, interdisciplinary work across basic science and engineering disciplines is particularly encouraged. The areas covered by the journal include, but are not limited to, materials and composites for photovoltaics and photoelectrochemistry, bioprocessing, batteries, fuel cells, supercapacitors, clean air, and devices with multifunctionality. The readership of the journal includes chemical, physical, biological, materials, and environmental scientists and engineers from academia, industry, and policy-making.
