The coating material disclosed by the invention has friction power generation and antifouling properties; according to the friction power generation coating, mechanical energy can be converted into electric energy, so that adhesion of organisms on the surface of the coating is inhibited, the antifouling effect can be improved, the obtainedcoating can be cured at normal temperature, has good environmental adaptability and constructability and can be applied onto the surfaces of various materials, and the application range of the friction power generation coating is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of triboelectric power generation coatings, in particular to an anti-biofouling triboelectric power generation coating material and its preparation method and application. Background technique [0002] Harvesting energy from the living environment is widely regarded as an effective way to achieve green energy and sustainable energy development, and is expected to play an important role in anti-fouling and anti-corrosion protection of materials, wireless transmission systems, and implanted medical devices. There are many forms of frictional energy in the natural environment, such as the friction between sea water and the hull, the friction between automobile tires and the ground, the friction between gear mechanisms, etc. If these abundant friction energy can be collected and utilized, not only can the energy pressure be greatly relieved, but also huge economic benefits can be generated. Based on the princip...
