Generalization of Humidity Effect on the Lateral Ordering of Hydrophilic Block Copolymer Thin Film |
| 초록 |
It has been demonstrated that block copolymer films of PEO-PS and PEO-PMMA-PS, with cylindrical microdomains of PEO or PEO-PMMA, have a high degree of lateral ordering. It was shown that relative humidity plays an important role in long-range as well as lateral ordering of the block copolymer thin films. However, the origin of the humidity effect on the lateral ordering is not yet fully understood. To investigate the effect of humidity further, we prepared other hydrophilic block copolymers, PDMA-PS, where hydrophilic PDMA is a cylindrical microdomain. As with PEO-containing block copolymers, it was shown that PDMA-PS block copolymers also exhibit the long-ranged lateral order after solvent annealing with a controlled humidity. This result suggests that the long-range lateral ordering is induced by the effect of humidity, and the incorporation of the hydrophilic component is a controlling key in this case. The detailed synthesis and their film morphologies will be presented. |
