Abstract
A gas diffusion barrier contains a polymer matrix and a functional graphene which displays no signature of graphite and/or graphite oxide, as determined by X-ray diffraction.
Claims20
A gas diffusion barrier, comprising:
- a polymer matrix;
- and
- a functional graphene having a surface area of from about 300 m2/g to 2600 m2/g, wherein said functional graphene is made by thermally exfoliating graphite oxide at a temperature of from 300 to 2000° C.
A process for manufacturing a gas diffusion barrier, comprising:
- adding a functional graphene having a surface area of from about 300 m2/g to 2600 m2/g, to a polymer matrix,
- wherein said functional graphene is made by thermally exfoliating graphite oxide at a temperature of from 300 to 2000° C.
