Embodiment 1

[0040] 1) Take an appropriate amount of liquid silica gel and propyl orthosilicate curing agent (the volume ratio of liquid silica gel and curing agent is 100:2.5), stir evenly in one direction with a glass rod; inject the liquid silica gel into the concave of the first step of the acrylic mold In a groove (55x115mm), wait for the silicone to fully cure at room temperature to obtain a silicone layer with a thickness of about 2.5mm.

[0041] 2) Take a flexible conductive cloth of a certain length and width, cut it into the desired shape (40x100mm), and spread it on the first layer of silicone sheet. A small tail should be left out of the conductive cloth to expose the silicone sheet, which is convenient for connecting wires later.

[0042] 3) Take an appropriate amount of liquid silica gel and propyl orthosilicate curing agent (the volume ratio of liquid silica gel and curing agent is 100:2.5), stir evenly in one direction with a glass rod; inject the liquid silica gel into the...

[0050] 1) Take an appropriate amount of liquid silica gel and propyl orthosilicate curing agent (the volume ratio of liquid silica gel and curing agent is 100:2.5), stir evenly in one direction with a glass rod; inject the liquid silica gel into the concave of the first step of the acrylic mold In a groove (55x65mm), wait for the silicone to fully cure at room temperature to obtain a silicone layer with a thickness of about 2.5mm.

[0051] 2) Take a flexible conductive cloth of a certain length and width, cut it into the desired shape (40x50mm), and spread it on the first layer of silicone sheet. A small tail should be left out of the conductive cloth to expose the silicone sheet, which is convenient for connecting wires later.

Abstract

The invention relates to a flexible single-electrode friction nano generator which comprises a three-layer structure, wherein the upper layer is a thin silica gel sheet used as a friction layer, the lower layer is a thick silica gel sheet used as a supporting layer, and flexible conductive cloth is arranged between the friction layer and the supporting layer. The flexible single-electrode friction nano generator S-TENG which is simple and easy to popularize is prepared by taking liquid silica gel, flexible conductive cloth, copper foils and copper wires as raw materials, and the prepared S-TENG has good flexibility, stability and a low-frequency mechanical energy collection function. Collected low-frequency mechanical energy can be effectively converted into electric energy, 240 LED lamp beads can be lightened, and an electronic watch and a small calculator can be driven. The nano generator has the advantages of being simple, low in cost, high in electrical output performance, good in stability and easy to produce on a large scale, and the prepared S-TENG sample has important potential application value in the fields of novel electronic devices and biomedicine.

Description

technical field [0001] The invention relates to the technical field of nano new energy devices and their preparation, in particular to a flexible single-electrode friction nano generator. Background technique [0002] With the development of the global economy and society, the energy problem has become a problem that everyone pays attention to and needs to be solved urgently. Traditional thermal power generation, wind energy, water energy and solar energy are all centralized energy supplies. In addition, there is a lot of low-frequency mechanical energy around us, which is often wasted. For example: the human body is doing some mechanical actions every day. If the clean energy is collected and converted into electrical energy, it can be used to power some portable electronic products. The emergence of triboelectric nanogenerators (TENGs) provides the possibility to realize this idea. TENGs have received extensive attention since they were discovered by Wang Zhonglin's gro...
