Based on specific interactions taking place between poly(N,N‐dimethylacrylamide) [PDMA] and silica nanoparticles, two strategies were used to improve the viscoelastic properties of aqueous formulations. First, PDMA oligomers were grafted onto a non‐adsorbing poly(acrylamide‐co‐sodium acrylate) backbone. With this architecture, the binding process of PDMA side‐chains with silica nanoparticles was shown...
The adsorption process onto a silica surface of oligomers from three different monomers, N,N‐dimethylacrylamide (DMA), N‐isopropylacrylamide (NIPA) and ethylene oxide (EO), was studied. From the adsorption isotherms and calorimetric experiments, it was shown that N‐alkylacrylamide derivatives strongly interact with silica nanoparticles. At low coverage (Γ < 0.5 mg m−2), the polymers were adsorbed...
Responsive thickeners have been obtained by grafting onto poly(sodium acrylate) [PAA] macromolecular stickers characterized by a lower critical solution temperature (LCST) in water: poly(N-isopropylacrylamide) [PNIPA] or poly(ethylene oxide-co-propylene oxide) [PPO]. As these LCST polymeric side chains are able to interact specifically with silica surfaces, while the macromolecular backbone does not,...
