| 제목 | Order and Structure in Thin Films of Side-Chain Liquid Crystalline Polymers |
| 초록 | With the aim of investigating the order and structure of thin films of side chain liquid crystalline polymers, a side chain liquid crystalline polymer containing a poly(oxyethylene) backbone and n-decylsulfonylmethyl side chains was synthesized. The inner structure, surface structure and near-substrate structure of thin film of these polymers were investigated. An X-ray reflectivity study of a polymer film spin-coated onto a silicon wafer showed that, upon annealing above the glass transition temperature, the film has a lamellar structure in which the ordered layers are parallel to the substrate surface. From NEXAFS spectroscopy, side chains were estimated to be tilted by 37° from the surface normal. The effect of substrate on the side chain orientation near the silicon substrate was investigated by x-ray reflectivity and ellipsometric experiments of thin films with different thicknesses. * This work was supported by the National Research Laboratory Program (Ministry of Science and Technology of Korea) |
