Hi Nowzesh,

Its Hydrophobic.........

But Gr can't float by itself.. Too much mechanical force. It will disintegrate on top of the solvent by itself, if you dont use PMMA. One of the main reason to use PMMA is also to provide mechanical rigidity to Gr during floating...

Hope this will give u some idea..

Best,
