GO in NMP - considering NMP is not an electrilyte on itself, can the flakes move towards the opposite electrode?
adding graphene oxide / rGO / graphene have shown conflicting surface roughness changes in Polyethersulfone. for rGO in specific, why do we have roughness decrease whilst porosity has increased?
