基于拱形单电极的摩擦纳米发电机（TENG）是使用还原氧化石墨烯纳米带（rGONR）薄膜和聚偏二氟乙烯（PVDF）聚合物作为粘合剂制成的，可有效地将机械能转化为电能。在 PVDF 聚合物中加入 rGONR 可提高 rGONR/PVDF 薄膜的平均表面粗糙度。平均粗糙度的提高和官能团的产生相结合，表明制备的薄膜的电荷存储能力得到提高。此外，与原始rGONR相比，通过循环伏安法获得的氧化还原峰在rGONR/PVDF复合材料中得到更多识别，以确认薄膜的电荷转移能力。本文通过实验和理论讨论了输出性能，得到的最大电压为0.35 V。新设计的TENG用于收集机械能，并在能量收集应用中开辟了许多新的研究途径。
The arch-shaped single electrode based triboelectric nanogenerator (TENG) is fabricated using thin film of reduced graphene oxide nanoribbons (rGONRs) with polyvinylidene fluoride (PVDF) polymer used as binder to effectively convert mechanical energy into electrical energy. The incorporation of rGONRs in PVDF polymer enhances average surface roughness of rGONRs/PVDF thin film. With the combination of the enhancement of average roughness and production of functional groups, which indicate improve charge storage capacity of prepared film. Furthermore, the redox peaks obtained through cyclic voltammetry were identified more in rGONRs/PVDF composite in comparison to pristine rGONRs to confirm charge transfer capability of film. Herein, the output performance was discussed experimentally as well as theoretically, maximum voltage was obtained to be 0.35 V. The newly designed TENG to harvest mechanical energy and opens up many new avenues of research in the energy harvesting applications.
