The application discloses a use of nicotine and its salt, a nicotine derivative and its salt in preparation of a marine biofouling antifouling agent. The application first discovers that nicotine can inhibit the adhesion of marine fouling organisms at a lower concentration. Nicotine has the characteristics of easy decomposition under light, does not pollute the marine environment, and can avoid the long-term influence on the marine ecological environment caused by the release in the marine environment. Meanwhile, nicotine can be dissolved in water and oil, is hydrophilic and lipophilic, is suitable for preparation of an antifouling coating, and can easily control the release speed, effectively avoid the burst release phenomenon of the antifouling agent, improve the utilization rate, and prolong the antifouling time. Nicotine is mainly extracted from tobacco and can also be prepared by chemical synthesis. Nicotine has a high content in tobacco and a mature extraction process, which provides a guarantee for the development of nicotine into an antifouling agent, and solves the problems of difficult extraction, difficult synthesis, low yield and difficult practical application and popularization of natural products in the development of natural antifouling agents.
