Scientists investigated a series of polyacrylamide resins with a self-generating hydrogel layer, which arises from the polymerization of acrylamide (AM), butyl acrylate, methacrylic acid and AM derivatives.
The search for robust antifouling coatings is a permanent goal for marine materials. Mechanical strength and thermal stability are markedly improved due to the change in the structure of the modified resins.
Preliminary results indicate that the resulting resins with cross-linking structure show satisfactory abrasion resistance and swelling properties. The results of the tests of anti-fouling panel in shallow immersion for three months reveal that the addition of acrylamide derivatives leads to the generation of a soft, thin and dynamic layer of hydrogel, which improves the antifouling properties. The formation of hydrogel and self-generating properties is promising in various antifouling applications.
