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 iron(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.
