Yuri Mirgorod

Dry functionalized graphene in a vacuum desiccator over anhydrous calcium chloride. Drying in a vacuum oven when heated can cause your gel to dehydrate and decompose. Preferably in glass cups.

Xuhua Wang

Following Yuri's suggestion, the centrifuge tubes are normally polypropylene materials. Cannot put into heated up oven. You have to take out your functionlised graphene oxide materials. Put them into a heat resistant beaker into the vacuum oven. Pumping down vacuum and at the meantime heating up around 105 degree C for hours. It should be able to remove moisture.

Sujoy Mandal

You take it in a beaker or sutaible container. rapped it by alumina foil to avoid light illumination. You can also dry it in a vacuum decicator with pumping by several hours repeatedly.
