Free-standing graphene oxide films/separators are made from single layered graphene oxide dispersed in DI water without the use of surfactant using a simple drop casting method.
The thickness of the graphene oxide films is adjustable.
Also, the transparency of the GO film is controlled accoridng to the film thickness.
SPECIFICATIONS

~500 nm, ~1 µm, ~2 µm
Applications
separators for advanced supercapacitors and batteries
