説明
Hydrophilic/hydrophobic block copolymer (poly(N, N'-dimethylacrylamide)-block-poly(glycidylmethacrylate) (PDMAA-b-PGMA)) as a solvent coating membrane sample was applied on the surface of polyurethane substrate, and it was the dried and annealed at 80-140°C. Before the sample was immersed in water, hydrophobic PGMA segment increased on the surface, and the segment increased with increasing drying temperature. When the samples dried at low temperatures (80°C, 100°C) were immersed in water, the composition of their coating membranes changed from PGMA segment-rich to PDMAA segment-rich, and the friction coefficient in water was about 0.03-0.04. The friction coefficient in water increased as drying temperature increased. Such behaviors were caused by the change in the surface structure, when immersed in water depending on the degree of PGMA segment enrichment.<br>It became obvious that, when immersed in water, the change and the stability of surface structure of the hydrophilic/hydrophobic block copolymer coating membrane greatly influenced the lubricity of the coating membrane.
