[0059] The preparation method of the above-mentioned semiconductor composite material will be described in detail below. The method includes: an optional step (1) modifying the metal particles, specifically using a modifier to treat the surface of the metal particles to obtain metal particles surface-modified by the modifier. The surface treatment method used in the present invention is a conventional metal particle surface treatment method.

[0060] (2) Prepare a liquid solution of the polymer base material. Specifically, polyvinylidene fluoride, polymethyl methacrylate or polyvinyl chloride are dissolved in dimethylacetamide (DMA) to form a liquid solution. Dimethicone itself is liquid and can be applied directly to the second step.

[0061] (3) Add metal particles to the liquid solution obtained in step (2) and mix well. When polydimethylsiloxane is used as the polymer, polydimethylsiloxane and curing agent (vulcanizing agent, usually at a ratio of 10:1) are required. Th...

Abstract

The invention provides a friction power generator employing a semiconductor composite material. The friction power generator comprises a first electrode layer, a first polymer material layer and a second electrode layer, which are laminated, wherein a material for the first polymer material layer is a metal-doped polymer semiconductor composite material. According to the friction power generator, an insulating polymer is doped with metal particles, so that the resistivity of the polymer is reduced, and the volume resistivity of the polymer is at a level between the volume resistivity of metal and the volume resistivity of an insulating material. According to the friction power generator, the working internal resistance of the power generator can be effectively reduced, and the load capacity of the friction power generator can be improved within a certain range.

Description

technical field [0001] The invention relates to the field of friction power generation, in particular to a friction generator using a metal-doped polymer semiconductor composite material. 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 triboelec...
