Abstract
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.
Highlights
Nowadays, energy harvesting is an area of immense interest because of the increasing energy demands of society to create self-powered and autonomous systems[1]
We have considered the combination of these elements as a rGONRs/polyvinylidene fluoride (PVDF) composite material
We have synthesized the rGONRs through unzipping of Carbon nanotubes (CNTs)
Summary
Energy harvesting is an area of immense interest because of the increasing energy demands of society to create self-powered and autonomous systems[1]. The triboelectric nanogenerator (TENGs)[10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33] are based on the phenomenon of electrostatic induction and triboelectric effect These nanogenerators are found to be reliable, flexible, worthwhile and highly competent device to harvest mechanical energy into electrical energy. Due to these unique properties, they are used in various other applications including supercapacitors[37,38], as a hole transporting material in solar cells[39,40], field effect transistors (FETs)[41] and biomedicals etc.[36,38] In this communication, we ripen a strategy pointing to construct TENG with one of its electrode of composite material which contains oxidized graphene nanoribbons and PVDF as binder. Our approach focus on efficient way to improve the performance of TENG
