纳米二氧化硅球如何用APTES氨基化？？?
|
| Fifty milliliters of ethanol and 50 mL of water were added to a 250 mL round-bottomed ask with a mechanical stirring bar.Ten milliliters of NH3·H2O was added, and the mixture was stirred at600 rpm. Five milliliters of TEOS was added drop by drop, and then the resultant mixture was stirred overnight. Five milliliters of APTES was then added, and the mixed solution was stirred for an additional 12 h.我参照这个合成的，合成二氧化硅球后直接加加APTEs,淡蓝色溶液变成了乳白色溶胶，是APTES量多了？还是由于烧瓶中还有水？请各位大神指导一下我该怎么氨基化呀？谢谢 |
