Abstract

According to one or more embodiments, a method of making an antifouling coating includes forming a polythioaminal polymer by reacting a fluorinated primary amine with an aldehyde to form an intermediate imine, and then reacting the intermediate imine with a dithiol. The method further includes depositing the polythioaminal on a substrate, and increasing a temperature of the polythioaminal deposited on the substrate to crosslink the polythioaminal and increase a contact angle of the substrate with crosslinked polythioaminal.
