Abstract

Poly(N-isopropylacrylamide) (PNIPAAM) exhibits a reversible, temperature-dependent transition at its lower critical solution temperature in aqueous media. When PNIPAAM molecules are covalently attached to a solid surface, the grafting density greatly affects the thermo-responsive wettability behavior of the PNIPAAM-modified surfaces.
