Discussion Overview
The discussion revolves around the feasibility of creating a Graphene or Graphene Oxide-based polyester film with significantly lower helium permeability than currently available materials. Participants explore potential methods for production, the types of processes and equipment required, and the achievable levels of permeability.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant questions the current possibility of creating a Graphene or Graphene Oxide-based polyester film with lower helium permeability and seeks insights on production methods and equipment.
- Another participant suggests that a reverse osmosis membrane could be relevant to the discussion, referencing research on nanoporous graphene as a potential solution.
- A third participant shares links to threads on Researchgate that discuss the production of free-standing graphene oxide membranes and the creation of graphene films.
- There is a mention of using polyvinylidene Chloride (PVDC) film in airship envelopes, proposing that a similar approach with polyester and a GO film could yield improvements.
Areas of Agreement / Disagreement
Participants have not reached a consensus on the feasibility or methods for creating the proposed material, and multiple viewpoints and suggestions are presented without resolution.
Contextual Notes
The discussion does not clarify specific assumptions regarding the properties of the materials or the technical limitations of the proposed methods, leaving several aspects unresolved.
