NPG Asia Materials - A liquid crystal-like transition between isotropic and nematic phases in liquid suspensions of graphene oxide holds promise for a range of applications.

The finding broadens scientists’ understanding of basic graphene chemistry and sounds a cautionary note about processing this 2D form of carbon, which is a common starting material for graphene ...

These tests confirmed that applying small amounts of graphene oxide increases barrier performance and paper strength by 30% to 50% over what is commonly used in the market.
