preparation example Construction

[0047] The preparation method of the above-mentioned high-power nano friction generator will be described in detail below. The method comprises the steps of:

[0048] (1) Preparation of a substrate with nanowires

[0049] ZnO nanowires are vertically grown on one surface of the substrate to obtain a substrate with nanowires.

[0050] The substrate that can be used in the present invention may be a silicon substrate, a gold-plated or chrome-plated glass substrate, or the like.

[0051] The present invention uses a conventional hydrothermal method to grow zinc oxide nanowire arrays, for example, hexamethylenetetramine (HMTA) and zinc nitrate hexahydrate (ZnNO 3 6(H 2 O)) mixture as a culture medium, at a suitable temperature such as 80-95 ° C, grow zinc oxide nanowire arrays on the silicon substrate. Specifically, in a specific embodiment, a zinc oxide seed layer with a thickness of 30-50 nm is formed on one surface of the silicon substrate by conventional sputtering. Using...

[0072] Such as figure 1 and 2 As shown, the size of the high-power nano triboelectric generator in this embodiment is 4.5cm (length) × 1.2cm (width), which includes the first electrode layer 1 (aluminum layer with a thickness of 0.1mm) stacked in sequence, high molecular polymer Layer 2 (1 mm thick polyvinylidene fluoride), and triboelectrode layer 3. The friction electrode layer 3 includes a friction film layer 31 (1.0mm thick coated paper (specification 200g / m 2 )) and a second electrode layer 32 (copper layer with a thickness of 0.1 mm), the friction film layer 31 is arranged opposite to the polymer layer 2 . The surface of the polymer layer 2 opposite to the triboelectrode layer 3 is provided with a plurality of nanopores 4 (with a width of about 60 nm, a depth of about 8 μm, and an average hole spacing of 9 μm). The first electrode layer 1 and the second electrode layer 32 are voltage and current output electrodes of the triboelectric generator.

[0073] The preparati...

Embodiment 2-3

[0084] Embodiment 2 and 3 adopt the method substantially identical with embodiment 1 to prepare, difference is listed in the following table:

[0085] Table 1

[0086]

[0087] Using a stepper motor with periodic oscillation (0.33Hz and 0.13% deformation) makes friction generator 2# and 3# undergo periodical bending and release, and the maximum output voltage and current signal of friction generator 2# reach 900V and 850μA respectively , the maximum output voltage and current signal of friction generator 3# reached 680V and 450μA respectively.

Abstract

The invention provides a high-power nanometer friction generator and a manufacturing method thereof. The high-power nanometer friction generator comprises a first electrode layer, a macromolecule polymer layer and a friction electrode layer which are sequentially overlaid; the surface, opposite to the friction electrode layer, of the macromolecule polymer layer is provided with a plurality of nanometer holes; the first electrode layer and the friction electrode layer are voltage and current output electrodes of the friction generator. Polyvinylidene fluoride provided with the nanometer holes serves as the macromolecule polymer layer for friction, the friction effect is good, voltage and current output is high, and high-energy output of the friction generator is achieved.

Description

technical field [0001] The invention relates to a friction generator, in particular to a high-power nanometer friction generator and a preparation method thereof. Background technique [0002] With the continuous improvement of modern living standards and the accelerated pace of life, self-generating equipment with convenient application and low dependence on the environment has emerged. Existing self-generating devices typically exploit the piezoelectric properties of materials. For example, in 2006, Wang Zhonglin, a professor at the Georgia Institute of Technology in the United States, successfully converted mechanical energy into electrical energy at the nanoscale, and developed the world's smallest generator - a nanogenerator. The fundamental principle of nanogenerators is that when nanowires (NWs) are dynamically stretched under an external force, piezoelectric potentials are generated in the nanowires, and corresponding transient currents flow at both ends to balance ...
