【摘要】 对Ｓｏｌ－ Ｇｅｌ 浸涂液稳定性的研究表明： 在酸催化条件下， 加水量对醇盐水解缩聚产物的结构有重要影响， 随Ｒ （ Ｈ２Ｏ／ＴＥＯＳ） 值增加， 浸涂液的稳定性提高， Ｒ≥１５ 的ＳｉＯ２ 质浸涂液更适合工业化的生产。在浸涂液中加入一定量的干燥控制化学剂（ＤＣＣＡ） 后， ＴｉＯ２ 及ＴｉＯ２ － ＳｉＯ２ 质浸涂液非常稳定。更多还原

【Abstract】 According to the research on the stability of the sol-gel solution, it is demonstrated that the water content R (H 2O/TEOS) acts as a very important function on the structure of poplmer from the condensation reaction of metal alkoxide, the stability of sol will enhance with the increasing of the water content; For R ≥15,SiO 2 sol is more suitable to industrial manufacture; The TiO 2 and TiO 2-SiO 2 sol became very stable by means of modified Ti(OBu) 4 or TEOS through DCCA(such as HCON(CH 3) 2 and AcAc).更多还原
