Abstract

A friction generator (1) and a preparation method therefor. The method comprises: step 1, coating nanometer particles on at least one side of a viscous material film, so as to obtain a nanometer film layer; and step 2, manufacturing a friction generator, wherein a first polymeric material layer (12) and / or a second polymeric material layer (23) and / or an intermediate film layer are composed of the nanometer film layer obtained in step 1. The generator can effectively reduce the viscosity which appears when the viscous material film generates friction on a smooth surface, so that the two friction layers can be separated quickly, and therefore, the friction generator can operate continually and steadily.

Description

technical field [0001] The invention relates to the field of nanometer materials, in particular to a friction generator using nanometer materials. Background technique [0002] At present, the energy issue is one of the major issues affecting human progress and sustainable development. Various researches on new energy development and reusable renewable energy are being carried out in full swing all over the world. [0003] Energy harvesting and conversion devices constructed using tribotechnology play a key role in self-powered nanosystems. Moreover, due to its environmental protection, low cost, self-driving and other characteristics, it has received extensive attention. Since the piezoelectric friction generator developed by Professor Wang Zhonglin's research group realized the conversion of mechanical energy into electrical energy, friction generators with different structures and materials based on piezoelectricity and triboelectricity have come out one after another. ...
