Here it is demonstrated that mesoporous silicas (MPSs) can be used as effective "topological crosslinkers" for poly(N-isopropylacrylamide) (PNIPA) hydrogels to improve the mechanical property. Three-dimensional bicontinuous mesporous silica is found to effectively reinforce the PNIPA hydrogels, as compared to nonporous silica and two-dimensional hexagonally ordered mesoporous silica.
