Abstract:
We developed a light-mediated, surface modification technique to encapsulate hydrogels in covalently bound, hydrophobic polymer coatings. Poly(acrylic acid) (PAA) hydrogel surfaces were photocatalytically decarboxylated and subsequently decorated with hydrophobic polyacrylates. These shell-encapsulated hydrogels exhibited excellent hydrophobicities and anti-swelling behaviors relative to unmodified PAA hydrogels.
