Abstract

The invention discloses a preparing method of a film having a micro-nano structure and a frictional electric generator adopting the film. The method includes: 1) a step of preparing a graphical template, namely a step of arranging a graphical metal wire layer on the surface at one side of a metal base layer to obtain the graphical template, with the metal wire layer being formed by graphical metal wires; and 2) a step of manufacturing a polymer film having one side that has the micro-nano structure, namely a step of coating the graphical template prepared in the step 1) with slurry of a polymer material, stripping from the template after the slurry is solidified to obtain the polymer film having one surface that has the micro-nano structure. The method can conveniently manufacture the frictional electric generator, and a manufacturing process is simple and low in cost.

Description

technical field [0001] The invention relates to the field of nanotechnology, in particular to a method for manufacturing a friction generator and the manufactured friction generator. Background technique [0002] Energy harvesting and conversion devices constructed using nanotechnology, which play a key role in self-powered nanosystems, have attracted increasing attention due to their environmental protection, energy-saving, and self-driving properties. Since the piezoelectric nanogenerator developed by Professor Wang Zhonglin's research group converted mechanical energy into electrical energy for the first time, nanogenerators with different structures and materials based on piezoelectricity and triboelectricity have come out one after another. [0003] The friction generator mainly uses the friction between polymer and polymer (metal) to generate static charge, and then generates induced charge on the electrode to form a potential difference to realize a generator that gen...
