【討論】新的氧化石墨烯的合成方法 已有8人參與
|

|
最近對石墨烯的合成比較感興趣,看了一些文獻 其中一篇是發(fā)在ACS NANO上,對他提出方法,由于還沒有動手做過,所以對與這種方法的可靠性,想請各位蟲子討論一下, 按照他的方法一步一步的能不能得到那么多的產(chǎn)量,還有就是他中間過濾時用的是什么膜?多大尺寸?是抽慮嗎? 懇請各位蟲子不吝賜教! 文章附上 http://g.zhubajie.com/urllink.php?id=10668849bmqn8d478new4xeu |

The filtrate was centrifuged (4000 rpm for 4 h), and the supernatant was decanted away. The remaining solid material was then washed in succession with 200 mL of water, 200 mL of 30% HCl, and 200 mL of ethanol (2); for each wash, the mixture was sifted through the U.S. Standard testing sieve and then filtered through polyester fiber with the filtrate being centrifuged (4000 rpm for 4 h) and the supernatant decanted away. The material remaining after this extended, multiple-wash process was coagulated with 200 mL of ether, |
