利用聚乙烯醇作载体,通过溶胶-凝胶使光敏变色材料与实体木材进行复合,制备具有在紫外光照射下能发生光敏变色的木质基功能材料。通过紫外光辐射前后色度指数、视觉效果比较分析了紫外光照射对木质基光敏变色功能材料表面色差指数的影响。结果表明,经紫外光辐射后材料表面色差值明显增加,光敏变色效果显著。
Photochromic materials and wood were composited by the sol-gel using polyvinyl alcohol as carriers to prepare wooden-base photochromic functional materials under the ultraviolet irradiation(UV-irradiation).Chromaticity indexes and visual effects before and after the UV-irradiation were compared to discuss the effects of UV-irradiation on the color difference indexes of wooden-base photochromic functional materials.It turned out that photosensitive color effects of the material surface were remarkable and color difference value increased significantly after the UV-irradiation.
