Preparing oversized single-layered graphene oxide, by reacting graphite, strong oxidizing agent, template protecting agent and acid, diluting acid with deionized water, removing residual oxidizing agent and centrifugally washing.

GAO C, LI P, XU Z

Preparing graphene oxide film for humidity detection, involves floating graphene oxide film on substrate liquid with specific thickness, and evaporating substrate liquid to obtain highly wrinkled graphene oxide film.

GAO C, PENG L, XU Z, GUO Y

Concentrating big sheet graphene oxide solution involves passing graphene oxide solution through slit, flowing for 1-2 minutes, coagulating oxidized graphene, centrifuging in bag, and then dehydrating, which has good dispersion.
