Description

technical field

[0001] The invention relates to the technical field of marine antifouling materials, in particular to an antifouling coating material and its preparation method and application. Background technique

[0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] Ships and offshore platforms serving in the complex and harsh marine environment have long been seriously harmed by marine biofouling. Antifouling coatings are currently the most effective, economical, and widely applicable antifouling strategies. Among them, low surface energy antifouling materials made of silicone resin or fluoropolymer can effectively prevent the attachment of marine fouling organisms, and weak water flow or simple...
