preparation example Construction

[0058] The preparation method of the above-mentioned semiconductor composite material will be described in detail below. The method includes:

[0059] (1) 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.

[0060] (2) Mix polyaniline with the liquid solution obtained in step (1), and then centrifuge. as well as

[0061] (3) Coating and drying the solution obtained by centrifugation to obtain a film with micro-nano concave-convex structure on at least one side surface or no micro-nano concave-convex structure on both side surfaces. The invention adopts methods such as conventional screen printing, coating, spin coating and the like to prepare a thin film with a concave-convex structure on a silicon template.

[0062] The invention adopts met...

Embodiment 1

[0085] Add 250g of polyaniline particles into 1000g of polydimethylsiloxane and mix evenly, centrifuge, apply the solution obtained by centrifugation evenly on the surface of the silicon template, and then use the method of spin coating to coat the excess silicon template surface The slurry is removed, forming a thin liquid film. The entire template was dried and peeled off in an environment of 85° C. to obtain a semiconductor composite film with a thickness of 150 um and a micro-nano concavo-convex structure with a protrusion height of 500 nm on one side.

Embodiment 2-3

[0087] The preparation method of Examples 2-3 is the same as that of Example 1, and the differences are shown in Table 2.

Abstract

The present invention provides a semiconductor composite material and a triboelectric generator using the composite material. In parts by weight, the semiconductor composite material includes: 100 parts of a polymer base material, and 5-50 parts of polyaniline particles. Using the semiconductor composite material in the triboelectric generator can effectively reduce the working internal resistance of the triboelectric generator, and can improve the load capacity of the triboelectric generator within a certain range.

Description

technical field [0001] The invention relates to the field of semiconductor composite materials, in particular to a friction generator using semiconductor composite materials to generate electricity by friction. 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 piezoel...
