| 제목 | UV protection effect of TiO2 loaded Illite |
| 초록 | Among clay minerals classified in Mica group, we selected illite as a substitution material of Tlac. Because illite is a 2:1 phyllosilicate mineral with tightly held, nonhydrated, interlayer K cations balancing a high layer charge. As with many clay minerals, illite contains both planar and edge sites available for metal uptake. Planar sites are due to a net negative structural charge resulting from isomorphic substitution in the octahedral and tetrahedral sheets, and edge sites are due to broken Al-OH and Si-OH bonds at the edges of the clay crystallite. The presence of planar sites in illitic clays has properties such as high porosity with strong adsorbability and excellent thermal resistance. Especially, this study reports the investigation of the effect of TiO2/illite as an inorganic UV blocking material for field that talc has been applied during the time . To obtain more accurate results, an improved scheme on light-object interactions based on recent progress in optical theory was proposed, describing how TiO2 react to the light illuminating on illite. |
