Polysulfobetaine methacrylate (PSBMA) that was hydrophobically modified with methacrylic acid 2,3-epoxypropyl ester (GMA) was synthesized via micellar copolymerization method. Viscosity of the hydrophobically modified PSBMA solution was sensitive to added salt concentration.

Microscope Technique

To improve the performance of traditional hydrogels, dually responsive multi-network hydrogel was designed and fabricated in two steps. Firstly, temperature-and pH-responsive copolymeric microgel of N-isopropylacrylamide, methacrylic acid and polyethyleneglycol methacrylate were prepared via precipitation polymerization in poly (vinyl alcohol) (PVA) aqueous solution. Then glutaraldehyde was added to the microgel dispersion to build crosslinks among microgels and PVA, producing multi-network hydrogel with thermo-and pH-sensitivity. The morphology of the microgel and hydrogel was characterized by electron microscope technique. Swelling and deswelling behaviors show that the obtained hydrogels exhibit good temperature-and pH-sensitivity. The hydrogel shows rapid deswelling kinetics and approaches deswelling equilibrium in ~30min.
