Abstract

The invention discloses an electrode of a triboelectric generator and a preparation method thereof. The electrode of the triboelectric generator comprises a porous electrode layer and a polymer layer, and the porous electrode layer and the polymer layer are embedded with each other to form a partial chimera or Complete chimera. The preparation method of the triboelectric generator electrode comprises the following steps: (1) brushing a layer of polymer layer on the surface of the template with a microstructure, and performing degassing treatment; (2) cutting the porous electrode layer with a flat surface into target size; (3) bonding the porous electrode layer on the surface of the polymer layer and performing curing treatment; (4) forming the polymer / electrode composite film from the surface of the template. The friction generator electrode of the present invention not only increases the firmness of the electrode so that it is not easy to fall off, but also improves the flexibility and power generation performance of the friction generator using the electrode.

Description

technical field [0001] The invention relates to an electrode of a friction generator, in particular to an electrode setting method of a friction generator and a preparation method of the electrode. 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] However, the electrode layer and the friction layer in the existing triboelectric generators have a stacked structure, that is, the two layers of materials are planar structures, and sputtered metal thin layer...
