Description
Technical Field
The invention relates to the technical field of friction power generation coatings, in particular to a biofouling prevention friction power generation coating material and a preparation method and application thereof.
Background
Energy is obtained from a living environment, is widely regarded as an effective way for realizing green energy and sustainable development of the energy, and is expected to play an important role in antifouling and anticorrosion protection of materials, wireless transmission systems and implanted medical devices. Various forms of friction energy exist in the natural environment, such as friction between seawater and a ship hull, friction between automobile tires and the ground, friction between gear mechanisms, and the like. If the abundant friction energy can be collected and utilized, the energy pressure can be greatly relieved, and great economic benefits can be generated. Based on the principle of triboelectrification and electrostatic induction, the coating prepared by simple and low-cost processing can finish high-efficiency acquisition of mechanical energy of the surrounding environment, and high output power density and energy conversion efficiency are realized. Researches find that the friction generator manufactured by utilizing the principles of friction electrification and electrostatic induction can effectively collect friction energy and convert the friction energy into electric energy to supply energy to the micro electronic device. Researchers have developed various forms of friction generators to realize the collection and utilization of friction energy.
The marine antifouling coating is an important protective material for marine ships and equipment, and the antifouling effect of the antifouling coating plays an important role in saving the sailing speed and energy of the ships. At present, the biofouling coating mainly utilizes the means of antifouling agents, low surface energy and the like to achieve the function of preventing biofouling adhesion.
Patents CN202818150U, CN203445807U, CN104052327A, etc. design friction power generation devices with different structures, and realize the collection of friction energy in various forms. The friction materials used in these devices are finished polymers and are very limited in irregular surface applications or large area applications. Meanwhile, the surfaces of the materials used in the patents all contain nano structures, so that the preparation cost is high, and the materials are easy to wear in the actual use process, thereby influencing the power generation efficiency. Patent CN20171022555.4 proposes an energy collecting coating material based on triboelectrification, which can be applied on irregular surfaces in large scale, however, the coating has a single function, and the light curing process has strict requirements on the construction environment. CN201410823167.8 relates to a low surface energy coating with a surface microstructure and a preparation method thereof, wherein the coating has antifouling and bactericidal synergistic effects.
However, none of the above methods combines the capture of frictional energy and anti-fouling properties into one coating, achieving simultaneous capture of energy and anti-fouling properties.
