Hi, how can I get a reduced graphene oxide in powder after centrifuged? I've tried to dry it in the oven but after 3 hours, it still in the solution form. Any other ways?
At which temperature you tried to dry the reduced graphene oxide and what was the solvent? If the centrifuged sample contins any other solvent except water such as DMF or any chemical reducing agent then it will be difficult to dry completely at low temperature (
The solvent is water. I already wash the reduced graphene oxide a few times during centrifugation. Will try freeze-drying method! Thanks :)
Hi everyone ! I have a question about this same topic. How long should you wait to freeze dry 200 mL water? I already started to try this method but after 20 minutes no water evaporated. I am thinking to distill the water under vacuum at room temperature, will the rGO stay as a pulver ? or what do you suggest?
is it the reduced graphene oxide need to centrifuge? how it wash? using di water only?
