Silica nanoparticles can be used as an adhesive for hydrogels or biological tissues due to the physical adsorption to polymer chains. Therefore, nanoparticle-mediated adhesion between polymer hydrogels is strongly related to the surface area as well as the morphology of the nanoparticles. It has been known that swelling ratio can affect the adhesion energy between hydrogels with nanoparticle-based adhesives because polymer density decreased simply. Here, when mesoporous nanoparticles are used as adhesives, we found that optimum pore size of mesoporous nanoparticles increased as the swelling ratio increased which is ascribed to that the swelling ratio lead to the change of the blob size of polymers in hydrogels. |
