Towards a responsive functional material: Modification of porosity and grafting of poly(N-isopropylacrylamide) in mesoporous silica SBA-15
Mesoporous silica materials, such as SBA-15, have potential as biocompatible carriers for pharmaceutical applications as well as mini-reactors in e.g. catalysis. This potential arises from their well-defined porous structure on the nanometre scale accompanied by a high internal surface area (800 - 1000 m2/g). This work addresses the following issues. i) Surface grafted PNIPAAM was found to be loca
