preparation example Construction

[0037] Wherein, the preparation method also includes steps after step (1):

[0038] Step (2) In order to prepare the positive electrode, the aluminum sheet was cut into a size of 4cm×4cm, then subjected to water-assisted oxidation treatment, and then fixedly connected to the acrylic glass substrate.

specific Embodiment 1

[0039] like figure 1 As shown, it is a self-powered nano triboelectric generator based on waste fluorinated rubber powder according to an embodiment of the present invention, including: a negative electrode 1 composed of waste fluorinated rubber powder and polydimethylsiloxane coated on Aluminum foil 2 and fixed on an acrylic substrate 4. Water-assisted alumina 3 was fixed on another acrylic substrate as the positive electrode. The two acrylic substrates are connected by four springs 5, and the wire 6 connects the upper layer of water-assisted alumina and the lower layer of aluminum foil electrodes.

[0040] Wherein, the upper layer of water-assisted alumina is rubbed with the lower layer of fluorinated rubber powder electrode by pressing to generate charges, because the triboelectricity of aluminum is higher than that of polydimethylsiloxane, so the water-assisted alumina is positively charged, The fluorinated rubber powder electrode is negatively charged. When the triboele...

Abstract

The invention relates to a self-powered nano triboelectricity generator based on waste viton powder and a preparation method. The method comprises the following steps that a positive electrode is subjected to water assisted oxidation treatment and then fixed to an acrylic acid base, polydimethylsiloxane is spin-coated on aluminum foil for pretreatment, the waste viton powder subjected to cleaning,screening and fluorination treatment is transferred to the surface of a polydimethylsiloxane film subjected to semi-vulcanization for full hard curing, then a product is fixed to another acrylic acidglass to serve as a negative electrode, and finally the positive electrode and the negative electrode are connected with a spring. The negative electrode is a waste viton and polydimethylsiloxane composite material, the positive electrode is water assisted aluminium oxide, and a large triboelectric order difference is provided. Accordingly, waste rubber difficult to degrade is fully utilized as araw material, and converted into a renewable energy source to be reused, and an effective method is provided for solving waste rubber reuse.

Description

technical field [0001] The invention belongs to the field of new energy development and nano power generation, in particular to a self-powered nano triboelectric generator based on waste fluorinated rubber powder. Background technique [0002] With the increasingly severe energy depletion and waste of resources, the method of obtaining energy from sustainable, renewable and environmentally friendly resources has become a hot issue and a feasible way to alleviate the energy crisis.
