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