ESTABLISHMENT OF MASS PRODUCTION METHOD OF MESOPOROUS SILICA THIN FILM AND DEVELOPMENT OF POROUS CARBON THIN FILM USING 1,4- DIHYDROXYANTHRAQUINONE AS CARBON SOURCE

摘要

Porous materials typified by mesoporous silica and porous carbon are expected to be applied in various fields such as adsorption, ion exchange, and engineering. In this research, we focused on mesoporous silica thin films and porous carbon thin films. For the mesoporous silica thin film, mass creation method was established the by introducing the roll-to-roll fabrication method. In this method, the pore size could be controlled by changing the molar ratio of the precursor solution, and the thickness of mesoporous silica film is controlled by changing the peripheral speed ratio. In the development of porous carbon thin film, we succeeded to express pores by using 1,4-dihydroxyanthraquinone as a carbon source. X-ray analysis and arithmetic mean roughness measurements were made on the fabricated carbon thin film. As a result, it was confirmed that the porous carbon thin film prepared in this study has a higher specific surface area than the porous carbon thin film synthesized by the conventional manufacturing method.
