A mixture of PDA-Si and zinc ethoxide was hydrolyzed by moisture in the air or by addition of aqueous ethanol at 40 ℃ for 5 h,both with and without heat treatment at 120 ℃.
将PDA-Si与锌乙醇盐水解和固化交联,形成聚酯/纳米氧化锌复合材料。
The problems and causes presented in the preparation of titanium tetraethoxide by conventional Nelles method have been discussed.
本文对传统的莱尼斯法制备钛乙醇盐的缺点作了分析，有针对性地对合成方法作了某些改进，醇盐产率有较大提高。
