Encapsulation of poly(N-isopropyl acrylamide) in silica: a stimuli-responsive porous hybrid material that incorporates molecular nano-valves

Polymer-silica membranes were supported on porous centrifugal filters, the encapsulated polymer molecules acting as nano-valves. Permeation experiments with aqueous solutions of poly(ethylene glycol) show that the membranes function as thermally switchable molecular filters.
