摘要

在这个数字化时代,利用废聚合物生产生物机械能引起了人们的广泛兴趣,因为这样做可以带来许多好处,包括:(i) 解决废料处理难题,以及废料在大气中的存在所造成的污染(空气、水、土壤);(ii) 确保以低成本提供清洁且负担得起的能源;(iii) 避免不断更换电池、充电和充电时的长电线等麻烦。在此,作者的目标是回收利用废旧材料,尤其是聚合物,同时牢记有效管理废物的 4R 原则。基于三电/压电效应的能量收集器可将振动波和材料变形产生的能量转化为电能。我们建造了一个混合能量收集器,用废聚合物作为三电活性层,用纳米材料涂层诱导压电效应,用铝作为电极。与基于废聚合物的原始能量收集器相比,该能量收集器在定性输入条件下的输出电压增强了 266.166%,在定量输入条件下(分别为 1 N、1.5 N 和 3 N)的输出电压分别增强了 375.374%、337.33% 和 287.308%。所开发的装置可驱动低功耗便携式电子设备,如 LED、计算器、电子表、温度计和计步器。

Scrap polymeric materials as hybrid energy harvesters

Producing biomechanical energy from waste polymer has attracted lot of interest in this digital era as a number of benefits can be accounted for this including: (i) addressing challenges in the disposal of waste materials, and pollution (air, water, soil) caused by their presence in the atmosphere (ii) ensuring clean and affordable energy at low cost (iii) avoiding the hassle of constant battery replacement, charging, and long wires for charging, and so on. Here, the authors aim at the recycling of waste materials, especially polymers, keeping the 4R’s of effective waste management in mind. Energy harvesters based on triboelectric/piezoelectric effects convert energy from vibrational waves and material deformations into electricity. A hybrid energy harvester is constructed, with waste polymer to act as the tribo-active layer, nanomaterial coating is applied to induce piezoelectricity and Al as the electrode. The energy harvester demonstrated an output voltage enhancement of 266.166% for qualitative input conditions and 375.374%, 337.33%, and 287.308% for quantized input conditions (1 N, 1.5 N, 3 N respectively) when compared with the performance of raw waste polymer-based energy harvester. The developed device could drive low-power portable electronic devices, such as LEDs, calculator, digital watch, thermometer and pedometer.
