tetraethoxysilane

The Epoxy/ TEOS, Epoxy/ GPTMS and Epoxy/ GPTMS-TEOS hybrid materials were prepared by the two-step method based on the precursors of tetraethoxysilane ( TEOS), ( 3-glycidoxypropyl) trimethoxysilane ( GPTMS).

本文采用二步法，以正硅酸乙酯TEOS、γ-缩水甘油醚基丙基三甲氧基硅烷GPTMS以及GPTMS-TEOS为无机组分前驱体，制备了Epoxv/TEOS、Epoxy/GPTMS、Zpoxy/GPTMS-TEOS杂化材料。

The amorphous sphere silica nanoparticles were produced by hydrolysis of tetraethoxysilane ( TEOS) under alkalic condition in reverse microemulsion formed by the system of Triton X-100/ hexanol/ cyclehexane/ amomia water.

采用Triton X-100/正己醇/环己烷/氨水体系配制反相微乳液，在碱性条件下正硅酸乙酯在反相微乳液中发生受控水解，合成了具有无定形结构的球形二氧化硅纳米粒子。

Methyl-situ-modified silica sols were obtained by hydrolysis and co-condensation reactions occurred in base-catalyzed system by carefully controlling the sol-gel process of Methyltriethoxysilane ( MTES) and Tetraethoxysilane ( TEOS).

在碱性条件下通过TEOS和MTES的共水解缩聚反应制备了单甲基原位改性的SiO2溶胶，并使用提拉法在K9玻璃基片上镀制了疏水减反膜。
