Precise design of polymer structures leads to the unique physical properties and excellent functions not only in the bulk but also at the interfaces. The cross-linked thin films of poly(2-methoxyethyl vinyl ether), which is water-soluble at room temperature, were prepared by living cationic polymerization and subsequent ultraviolet light irradiation. The obtained films were thickened in water. The moduli of the hydrogel films near the water interfaces examined by force-distance curve measurements using atomic force microscopy were greatly sensitive to the cross-linking density of the polymers. Diffuse interfaces of the polymer chains at the water interface made it possible to prevent the platelet adhesion on the films. To further explore unique interfacial properties of hydrophilic polymers in water, we examined the preparation of graft layers of alternating copolymers of vinyl ethers and acrylates with oxyethylene side-chains onto substrates based on nitroxide-mediated radical polymerization using a surface-immobilized initiator. |
