Hybrid self-assemblies based on the adsorption process of poly(N,N-dimethylacrylamide)[PDMA],poly(N-isopropylacrylamide)[PNIPA] or poly(ethylene oxide)[PEO] with silica nanoparticles are reported.From adsorption isotherms and calorimetric experiments,it is shown that N-alkylacrylamide derivatives strongly interact with silica surfaces while PEO chains exhibit lower affinity.When such oligomers are grafted onto a non-adsorbing poly(acrylamide-co-sodium acrylate)backbone [PAMH],the binding process of these adsorbing side-chains with silica nanoparticles proceeds very similarly and gives rise to the formation of hybrid hydrogels as sketched in Figure 1 below.
