Abstract

The invention provides an anti-biofouling triboelectric coating material and its preparation method and application, and relates to the technical field of triboelectric coatings. The coating prepared by using the anti-biofouling triboelectric power generation coating material of the present invention not only has good triboelectric performance, but also can effectively collect friction energy in the environment, and the current generated during the test friction process is 0.1-30μA, The voltage is 1-200V; it also has good anti-biofouling property and has a protective effect on the base material, and the area covered by the bio-fouling is 3-10%. The coating material of the present invention has both triboelectric power generation and antifouling properties, can convert mechanical energy into electrical energy, thereby inhibiting the adhesion of organisms on the surface of the coating, and can improve the antifouling effect, and the obtained coating can be cured at room temperature, and has a good environment Adaptability and constructability, it can be coated on the surface of various materials, which greatly expands the application range of triboelectric coatings.

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...
