| Research Abstract |
Polymer brash that is a method to make thick functional group layer on a solid surface is paid attention recent years. In this research, we developed new method to built up the functional polymer brash consisted of hyperbranched siloxanes (hyperbranched siloxysilanes)(HBPS) on the inorganic oxides surface, and apply these to eco-materials such as "green cheromatography". In this year, as a continuous research from the last year, we investigated preparation of funtionalized HBPS. Although HBPS itself had strong interaction against inorganic surface, we introduced triethoxysilyl functional group into HBPS. The funtionalized HBPS was adsorbed on the surface of silicon wafer, and measured the active contact angles against water. When the triethoxysilyl group was introduced at the focal point of HBPS, it was interesting tat the surface was hydrophobic in the air while that was hydrophilic in the water. On the other hand, triethoxysilyl group was introduced at the terminal position, the surface was kept as hydrophobic. Next, we immobilized biotin protein on the triethoxysilyl HBPS modified glass surface, and found that the protein was nicely kept on the surface.
