Hierarchical Mesoscopic Structures of Polymer Complexes

这项研究是表面分析物理学家和薄膜制备聚合物化学家之间的合作研究。这项研究的目的是利用分子和分子组装的自组装和自组织来构建从纳米到微米尺度的二维聚合物络合物的分级结构。在金表面制备了碱基两亲核酸单分子自组装膜。用表面等离子体共振技术观察到了单层界面上互补碱基配对的形成。采用简单浇铸法制备了具有生物相容性的蜂窝图案薄膜。用等离子体共振显微镜观察了图案化聚合物薄膜的二维形貌作为对比图像。

This study is cooperative research between physicists of the surface analysis and polymer chemists of thin film preparation. The purpose of this study is hierarchical structuring of the two-dimensional polymer complexes from nanometer to micrometer scale by using self-assembling and self-organization of molecules and molecular assemblies. Self-assembled monolayers of nucleobase amphiphile were preapered on gold surface. The formation of the complementary base pairing at the monolayer interface was observed by surface plasmon resonance technique. A honeycomb patterned film having bio-compatibility was prepared by the simple casting method. The two-dimensional topography of the patterned polymer thin film was observed as contrast image of the plasmon resonance microscope.
