關(guān)于氧化石墨烯還原后處理的問題... 已有2人參與
|
||
| 將氧化石墨烯(GO)還原后再應(yīng)該在么處理?怎么干燥?我看文獻(xiàn)上許多都說離心水洗,試過離心,轉(zhuǎn)速10000rpm,感覺離心不了,石墨烯還是均勻分散在水中。可不可以直接過濾干燥呀? |

好像可以啊,這是我看到的一篇文獻(xiàn):Preparation of a batch of a colloidal suspension of reduced graphene oxide Graphite oxide (GO) was synthesized from natural graphite(SP-1, Bay Carbon, MI) by the modified Hummers method. A colloidal suspension of graphene oxide platelets in puri-fied water (50 mg of GO, 3 mg/ml) was prepared in a 250 ml flask with 2 h of bath ultrasound (VWR B2500A-MT). A sus-pension of graphene oxide in the H2O/N,N -dimethylformam-ide (DMF) solvent mixture was obtained by addition of DMF(volume ratio of DMF:H2O = 9:1) into the aqueous grapheneoxide suspensions. Hydrazine monohydrate (1 l l per 3 mg ofGO) (98%, Aldrich) was subsequently added to the suspension. Additional stirring with a Teflon-coated stirring bar at 80℃ for 12 h yielded a black suspension of reduced graphene oxide platelets. |
