Graphene/GO-based elastic material

[John Doe 93]

Is it currently possible to create a Graphene or Graphene Oxide-based polyester film, but with significantly lower helium permeability than currenlty avalible materials?

What would be the best way to create such a material and what type of processes and equipment would be involved in the production? How low permeability could realistically be achieved ?

A search for "graphene osmosis" found this, plus other hits. A reverse osmosis membrane sounds close to what you're imagining.

I found these threads on Researchgate:

Airship envelopes are lined with polyvinylidene Chloride (PVDC) film, bonded to the fabric.
If the same could be done with polyester and a GO film I imagine it would be an improvement over PVDC...
