Graphene Morphs From Hydrophobic To Hydrophilic

February 14, 2014August 7, 2014 Pooja Kashyap

Graphene is taking the role of Zeus in the fraternity of materials. Its astounding properties come to the fore every time researchers try to do something new with it. Interestingly this time, the material has shown its ‘romantic inclination’ towards water. Its hydrophobic nature allows graphene to repel water however, narrow capillaries fabricated from the material reverses the nature of the same material, turning it into hydrophilic. Rapid permeation occurs when the layer of water molecule is of same dimension as that of graphene itself, that is, one atomic thickness.
