Though nano TiO2 particles are good for phtocatalytic reaction, they agglomerate easily in the water. The phenomenon makes it hard for us to use. In this study the surfaces of nano TiO2 are treated with silane to avoid agglomeration. We found that 0.5~1.5% of silane should provide adequate coating. However, too much dose of silane may degrade catalytic reaction. An Acrylic non-woven cloth was chosen as the substrate material for wallpaper. We found that the gas flow rate or air breath is sensitive to the hot press temperature. The hot press temperature of 200-210 ℃ seemed to be the best. The main objective of this study is to define the best process for bacteria (E-coli) screening/elimination by means of photocatalytic reaction. The process involves the uniform dispersion and stable binding of TiO2 nano-particles onto non-woven cloth, and maintaining of good air breath. It is noted that the wallpaper will be used in the interior of houses or office buildings. Thus the UV light of lower energy, say, UV-A (365 nm wavelength) was adopted for disinfecting exposure. A regular fluorescent light was also used for comparison. The exposure distance and time of 20~30 cm and 2~4 hours respectively were found to be adequate for achieving the disinfecting purpose. The processes of press-soaking, hot pressing were used for making smart architecture materials. We tested samples with SEM, EDS, DSC, TGA, disinfecting percent and Methylene Blue, …etc., to find out the optimal parameters. Fong Ming Lee 李豐明 2004 學位論文 ; thesis 99 zh-TW |
