碩士 === 南臺科技大學 === 化學工程與材枓工程系 === 106 === IR shield painting was prepared by using the silanes modified indium tin oxide (ITO) particles dispersion within water-based polymer latices in this study. The silanes modified ITO was manufactured by using ball milling with silanes and identified by using FTIR and SEM-EDS measurement. The characteristic peaks of silane appeared at 2900 cm-1 and 1080 cm-1 in FTIR spectrum and the particle size of ITO was about 100 nm from TEM micrographs. In addition, amount of silanes grafting on ITO was calculated at 3.5 wt.% from the result of TGA analysis. Furthermore, the IR shield film with thickness of 7 μm to 20 μm was formed on glass substrate by using spin coating and the microwave drying process. The hardness of IR shield film dried by an 800 W microwave for 1 min was 9 H which was superior to 80 ° C heating oven drying for 30 min. The result of UV-Vis-NIR measurement shows that the IR shield film has a transparency of 85% in visible light , and can shielding 70% from 1,500 nm to 2,500 nm wavelength infrared.
