dc.description.abstract | Characterization and evaluation of PI/PVDF-TrFE composite nanofiber based triboelectric nanogenerators depending on types of electrospinning nozzle systems Xinwei Wu Dept. of Mechanical Design The Graduate School Hanyang University Recently, energy problems have become a hot spot of global concern. In order to solve the energy problem, people have developed a variety of energy harvesters, in which triboelectric nanogenerator (TENG) is a portable energy harvester. It has attracted attention because of its high output power, simple, and low-cost structure. In order to improve the performance of TENG, many studies have been performed such as increasing the surface charge density and increasing the contact area. In this study, using designed single-nozzle, conjugated-nozzle and multi-nozzle three electrospinning nozzle systems successfully fabricated different forms of PI/PVDF-TrFE composite nanofibers. These three forms of composite nanofibers were made as the dielectric layer of TENG, and the electrical properties of TENG were measured. Among them, multi-nozzle nanofibers showed the highest open-circuit voltage of 364 V and short-circuit current of 17.2 μA, respectively. The power density of TENG made with multi-nozzle nanofibers is 1.18 W/m2. It was able to stably harvest energy during the tapping experiment of 10,000 cycles and even from palm and foot tapping. The M-TENG could be used for various practical applications such as capacitor charging and LED lighting. | - |
