摘要： Provided are a surface zwitterionized silicone antifouling coating and a preparation method thereof. In the disclosure, hydroxyl-terminated polydimethylsiloxane and N-aminoethyl-3-aminopropyl methyl dimethoxysilane are used as raw materials, and tetramethylammonium hydroxide pentahydrate is used as a catalyst, thereby preparing a series of polydimethylsiloxane resins containing amino side chains in different proportions; then side chain amino modified polydimethylsiloxane is crosslinked and cured by using 3-glycidyloxypropyltrimethoxysilane as a curing agent; after that, the cured silicone coating is soaked in a solution of 1,3-propane sultone in acetone for ionization.
