During transfer of graphene from Cu foil to SiO2 we use acetone to remove PMMA from graphene surface, is there any effect of acetone on graphene's chemical or electrical properties.
Dear Mr Singla.
Anything that absorbs onto Graphene has an effect in the electrical properties.
Regards
There is no contradiction between the 2 former replies. The properties of graphene will be temporarily affected by adsorbed acetone at the moment of dissolving PMMA, but if the material is rinsed correctly with very pure acetone which is subsequently evaporated completely, then the properties must be reversibly restored.

@Minas. Are you aware of the difference between graphene and graphene oxide (GO)? When you said graphene is almost insoluble in acetone, do you mean the same for GO. I am asking because it looks like you used the paper that discussed the dispersion behavior of GO in various solvents to support your statement on graphene solubility.
Same question,
I am using acetone as a solvent for my pvdf membrane. I want to modify it with GO. Do u think it will be good for me to acetone as a solvent for pvdf/go membrane?
i don't know graphene oxide will be okay with acetone or not? I know NMP is a good option for GO dispersion and solubility but acetone is better for my application.
Kindly suggest...
Dear Usaid,
GO solubility is limited in acetone. I recommend to find another polar solvent (e.g. THF). You can be advised the following link in order to choose a more suitable solvent.
