What are graphene membranes?

In this video we explain what graphene membranes are.
Membranes can be made from graphene oxide, which is a form of graphene. Learn how the graphene oxide flakes stack together to form a laminate which forms a small spaces capable of blocking gases molecules including the smallest of gas molecules, helium.
Treatments can be added to block gases or liquids which opens multiple possibilities including clean water processing, improved anti-corrosion paint and smart food packaging.

Wow graphene looks so promising I'm surprised they haven't tried to inject it into our bodies yet.........oh wait nvm.

[@fritzwilhelm8258]

is it reduced graphene oxide that blocks both water AND gas? does the unreduced graphene oxide block gases but not water?
Thanks,

Alright Brits, you guys invented Graphene, us Americans are sold on it. So like...lets start manufacturing the material and get it in the hands of our tech companies. At this point I'm unsure as to why these videos are still being made, advertising the possibilities of Graphene. As a tech entrepreneur and business owner myself, I'm sold. Let's start talking manufacturing dates, pricing and when we can start building prototypes with the material. I'm sure I can think of even more possibilities and opportunities for the material than academics can.

+Lee's Legion still too expensive and/or too hard to produce in large quantities though...

+Dexter2020 Fair. They invented a way to isolate Graphene from Graphite using sticky tape. So technically you are correct.
