ABSTRACT
In this article, a new method is used to fabricate a high-performance triboelectric nanogenerator (TENG), which is convenient and cost-effective. A polyformaldehyde (POM) film with novel structures is prepared through electrospinning and is combined with a polytetrafluoroethylene (PTFE) film to assemble micro-nano structured TENG. The short-circuit current (I s) and open-circuit voltage (V o) of the TENG are up to 0.4343 mA and 236.8 V, respectively, and no significant change is observed by applying different frequencies of external impact forces from 1 to 10 Hz. Finally, we successfully drive an electrochromic device (ECD) directly using TENG within just 2 min for the first time.

Mentions: In order to further increase the electric output of TENG, we prepared a micro-nano structured POM film since charges generated by friction are largely decided by the surface morphology of friction materials [21]. Utilizing electrospinning technology simplifies its preparation process, and the POM film with special structures is obtained through adjusting the electrospinning parameters. As shown in Fig. 3a, the POM fibers are randomly oriented with uniform diameters ranging from about 500 to 800 nm. Particularly, porous nanostructures are formed on the surface of the fibers. According to reported studies, rough surface with micro-nano structures and porous structures could enhance friction and increase contact area [10, 11, 22]. Thus, this novel micro-nano structure is supposed to enhance friction and to increase the electric output of TENG. In addition, the nanoscale cracks on the surface of the commercial PTFE film (Fig. 3b) are advantageous to the enhancement of friction. Consequently, more electrostatic charges will be generated and distributed on the surfaces of POM and PTFE after friction, which could help improve the performance of our TENG.Fig. 3
