Towards a responsive functional material: Modification of porosity and grafting of poly(N-isopropylacrylamide) in mesoporous silica SBA-15
Popular Abstract in English Figure 1: Electron microscopy image of mesoporous material seen from above. The left image shows a possible shape of a silica particle (scale bar: 1 μm). The right image shows the mesopores in the particle (grey color) with the silicon dioxide walls (black color) (scale bar: 150 nm). Poly(N-isopropylacrylamide) (PNIPAAM) is a polymer that can provide the active part forMesoporous 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
