Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments, structural features and effects of the present invention will be made with reference to the accompanying drawings and examples.
Example 1
The invention provides an ocean liquid-solid contact electrification power generation unit, which comprises a substrate 1, an electrode layer 2, a graphene layer 3 and a high polymer material layer 4, as shown in figure 1. The material of the substrate 1 is acrylic plate or foam plate. The substrate 1 has a flat plate shape. The material of the electrode layer 2 is gold, silver, platinum, or an alloy material containing gold, silver, platinum. The electrode layer 2 covers the side surface of the base body 1 and one end of the base body 1. The electrode layer 2 covers one end of the substrate 1 for connection to an external circuit. The graphene layer 3 covers the electrode layer 2 on the side of the substrate 1. That is to say the graphene layer 3 covers all sides of the substrate 1. The number of graphene layers in the graphene layer 3 is greater than 1 and less than 10. The polymer material layer 4 covers the graphene layer 3 on the side surface of the substrate 1 and the other end of the substrate 1. The polymer material layer 4 is a triboelectric material. When the liquid rubs against the polymer material layer 4, electric charges are generated in the polymer material layer 4. Preferably, the material of the polymer material layer 4 is polyimide, aniline formaldehyde resin, polytetrafluoroethylene, and fluorinated ethylene propylene.
When the liquid-solid contact electrification generating unit is used, an external circuit is connected with the liquid-solid contact electrification generating unit and the reference electrode, and the reference electrode and the liquid-solid contact electrification generating unit are placed in liquid. The liquid is water, seawater, aqueous solution, etc., and the liquid may also be a liquid metal, such as mercury or gallium. When liquid fluctuates or flows, the polymer material layer 4 in the liquid-solid contact electrification generating unit provided by the invention rubs with the liquid, so that the surface of the polymer material layer 4 is charged, charges with different signs are induced on the surface of the composite structure of the electrode layer 2 and the graphene layer 3, and charge flow is formed between the liquid-solid contact electrification generating unit provided by the invention and the reference electrode through an external circuit. According to the invention, the graphene layer 3 is arranged on the surface of the electrode layer 2, and the good conductive characteristic of the graphene layer 3 is utilized, so that the electrode layer 2 and graphene layer 3 composite structure generates more charges, and the service life of the charges is prolonged, thereby increasing the quantity of the transferred charges per unit area, and improving the power generation efficiency. Therefore, the invention has the advantage of high power generation efficiency and has good application prospect in the field of ocean power generation.
Example 2
In example 1, as shown in fig. 2, pits 5 are provided in the surface of the polymer material layer 4. The pits 5 are tapered or four-sided tapered. The depth of the pits 5 is less than two thirds of the thickness of the polymer material layer 4. In this way, not only is the contact area of the liquid and the solid increased, but also more charges are generated by friction; but also reduces the distance between the charge generated by the friction and the graphene layer 3. The two effects make the electric charge generated by friction sufficiently transferred, thereby realizing stronger current in an external circuit and improving the power generation efficiency.
Example 3
On the basis of embodiment 2, the polymer material layer 4 is provided with graphene fragments, and the graphene fragments are in contact with the graphene layer 3. Thus, the electric charge generated by friction can be more quickly and more inducted, so that stronger current is formed in an external circuit, and the power generation efficiency is improved.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
