Moreover, Chinese patents CN202818150U, CN203445807U, CN104052327A, etc. have designed friction power generation devices with different structures, which have realized the collection of various forms of friction energy; however, the friction materials used in these devices are finished polymers, which are constructed on irregular surfaces or large areas The application will be greatly restricted; at the same time, the surface of the material used in this patent has a nanostructure, the preparation cost is high, and it is easy to wear during actual use, which affects its power generation efficiency
Chinese patent CN201710225554 proposes an energy-harvesting coating material based on triboelectricity, which can be coated on a large scale on irregular surfaces. However, the function of this coating is single, and the photocuring process has strict requirements on the construction environment.
However, none of the above methods has achieved the combination of energy harvesting and corrosion protection

Abstract

The invention provides an anti-corrosion friction power generation coating material and a preparation method and application thereof, belonging to the technical field of coating materials. The anti-corrosion friction power generation coating material provided by the invention has good triboelectrification performance, can be applied to the surfaces of various conductive materials, and can effectively collect friction energy (such as wave energy) in an environment; ad meanwhile, a coating formed by the anti-corrosion friction power generation coating material provided by the invention has goodanti-corrosion performance, has a protection effect on a base material, and can effectively protect the base material in an ocean from being damaged by corrosion. The anti-corrosion friction power generation coating material provided by the invention can be used as an anti-corrosion power generation coating of overwater equipment (such as ships, maritime work equipment or overwater buoys) in a water environment (such as oceans, rivers, lakes and seas), and electric energy generated by friction can play roles in illumination, driving, sensing, cathodic protection, corrosion protection and the like.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to an anti-corrosion friction power generation coating material and its preparation method and application. Background technique [0002] Ocean energy has the advantages of large reserves and a wide area. However, compared with renewable energy such as wind energy and solar energy, its conversion and utilization of electric energy has always been full of challenges. In the ocean, whether it is waves, tides, or currents, its movement frequency is relatively high. Low, between 0.1 and 5Hz, and these movements are irregular, it is difficult to use electromagnetic generators to effectively collect and transform energy. In addition, the problem of marine corrosion is also a stumbling block to the development and utilization of marine resources. Marine corrosion will not only cause economic losses, but may also cause catastrophic accidents such as rupture of oil pipelines and sh...
