Graphene oxide synthesis methods have been known for decades.Originally called graphite oxide,it is a compound of carbon,oxygen and hydrogen in various ratios.It is synthesized by exfoliating graphite with strong oxiddizersmrinsed repeatedly until the rinse water is PH neutral and then freeze dried to preserve solubility.Many companies try to reduce the rinsing or skip the freeze dryong but they are critical to success in using the product.The bulk product is brownish/yellowish solid material that retains the layer structure of graphite but with a mich larger and irregulat spacing.It does not require post production functionalization as it consists of graphene sheets with hydroxyl,carboxyl and epoxide groups.It is soluble in Di water,NMP,DMF,THF,Ethanol,and other solvents that behave like water.Graphene oxide can be reduced using serval method such as laser,microwave,electrochemically,hydrazine cvapor treatment,or by annealing at temperature from 250-400C in a forming gas(95% argon,5%hydrogen)environment yielding the intrinsically high electrical and thermal conductivity of graphene.
