Control of molecular transport through stimuli-responsive ordered mesoporous materials

Published

Journal Article

The design, synthesis, and characterization of materials with well-defined porous networks of molecular dimensions in which the size and surface energy of the pores can be externally and reversibly controlled to dynamically modulate the adsorption and tansport of molecular species are presented. Such methods are based on the formation of ordered mesoporous architectures via surfactant-templated sol-gel processing and control of transport and surface properties of the mesoporous materials through their modification by atom transfer radical polymerization (ATRP) of N-isopropyl acrylamide. Results show that the presence of poly(N-isopropyl acrylamide) (PNIPAAm), a stimuli responsive polymer (SRP), in the porous network can be used to modulate the transport of aqueous solutes.
