Versatile, Tannic Acid-Mediated Surface PEGylation for Marine Antifouling Applications Suyeob Kim Taewoo Gim Sung Min Kang 10.1021/acsami.5b01304.s001 https://acs.figshare.com/articles/journal_contribution/Versatile_Tannic_Acid_Mediated_Surface_PEGylation_for_Marine_Antifouling_Applications/2181604 In this study, we report a facile and versatile approach to the formation of marine antifouling surface coatings. The approach consists of a combined coating of polydopamine (pDA) and tannic acid (TA) and subsequent immobilization of polyethylene glycol (PEG) on solid substrates. TA coating of a pDA-coated surface was carried out using ironĀ­(III) coordination chemistry, and PEG was immobilized on the TA-coated surface via hydrogen bond formation. Stainless steel and nylon were successfully modified by this approach, and the resulting substrates were used for marine antifouling applications, in which diatom adhesion was significantly inhibited. Advantageously, this approach allowed marine antifouling coatings to be prepared by a simple immersion process under environmentally friendly conditions. 2015-04-01 00:00:00 Stainless steel PEG marine antifouling applications TA coating diatom adhesion Marine Antifouling ApplicationsIn tannic acid approach immersion process polyethylene glycol marine antifouling surface coatings substrate hydrogen bond formation marine antifouling coatings
