Thermo-responsive hydrogels containing mesoporous silica toward controlled and sustainable releases

摘要

Here we prepare thermo-responsive hydrogel containing mesoporous silica (KIT -6) with high surface area. Our hybrid hydrogel is prepared by gelation of NIPAM monomer with mesoporous silica particles in presence of cross linker. Owing to the doped mesoporous silica, a large amount of guest molecules are adsorbed easily. With increase of temperature, the hybrid hydrogel shrinks to retard the release of guest molecules.
