溶胶 -凝胶技术是制备有机 -无机杂化材料的重要手段 ,在光致变色、光纤传感和发光等光化学杂化材料制备方面应用前景广阔。提高光致变色染料的稳定性、制备溶胶 -凝胶光纤及降低杂化材料羟基含量是目前的研究重点。
Sol-gel technology is an important method to prepare organic-inorganic hybrid materials, and has broad application prospect in the preparation of photochemical hybrid materials such as photochromism, optical fiber sensing and luminescence. To improve the stability of photochromic dyes, the preparation of sol-gel optical fiber and reduce the hydroxyl content of hybrid materials is the current research focus.
