Electromagnetic polymer composite material for anti-fouling effect
The antifouling coating is a composite material consisting of fluorinated electroactive bipolymers and magnetic particles. This composite material is coated on a solid surface to make a smooth durable grassy coating. The coating generates electrical current when an electrolytic liquid flows over it, which prevents bacterial cells from attaching to the surface. It prevents virus and protein attachment. It also prevents chemical corrosion of a surface. The composite material itself, and the antifouling method that uses fluoride compounds and electrical current that is generated by the fluid flow are disclosed for a patent. The composite material can be applied to medical devices, biomedical devices, industrial equipment, ship's hulls, food processing equipment, food processors, drinking water distribution systems, and home electrical appliances.
