Problems solved by technology

This method has the disadvantages of high cost and complicated process, which is not conducive to industrial production.
[0003] In addition, the surface microstructure can also be made by using the sacrificial layer template method, which is generally to prepare a polydimethylsiloxane film with a surface microstructure. However, the price of materials used in this method is generally high, and the fabrication The strength and toughness of the sacrificial layer template are not ideal, so that the template is deformed during the high-temperature curing of polydimethylsiloxane, which affects the film-forming effect, which further affects the performance of the polydimethylsiloxane film in the triboelectric generator. application, and it is not conducive to the preparation and industrial production of friction generators
