GRAPHENE -Went down the Graphene rabbit hole.
It runs deep, very deep.
Yet... there maybe a shortcut to demystifying it's allure.
Graphene is currently produced at around
$200,000 per ton
$200 per kilogram (kg)
As one can read, it's very pricey.
Hence why many scientists are trying every angle to produce graphene.
Single atom layer sheets.
But.... is it practicle ?
I'd say... too thin.
Graphite is... graphene.
Graphene layers make up the structure of graphite.
YET... this is not the whole story.
If you search out what is the formula of graphite you'll get -
Carbon.
Flake graphite has structure.
Skeletle structure.
So does crystaline graphite.
Crystaline structure.
If one ventures the road of, graphite pencil smeared on paper they call it
graphene.... several layers of, greasy graphene.
Crystal graphene sheets ( layers )
Greasy graphene smeared ( layers )
Greasy graphite - not strong on own... but could be applied to - surfaces, films, membranes.
Crystalaline graphite - picking apart layers is not practicle.
So what's not being spoken about ?
Crystaline grahite / graphene has.... crystaline structure which make it
structurally strong.
What is the crystaline ?
Silica. lol
Does graphite + silica exist in nature - yes.
Silica carbide.
Take a wild guess what silica carbide is used for ?
Semi conductor chips.
So.... while scientist work the single layer impossible and investors sit and wait....
What else is going on ?
Don't blink.
Graphite + Silica deposits scooped up on the cheap.
Graphite and Silica 2 most important ingredients in, chip making, quantum, AI.
Kimberlite Diamond ( is silica )
^^^ Traditionally it is classified as silica under-saturated rock,
rich in olivine and Mg-rich mica
Graphite and Silicate deposits aggressively scooped ?
That tells me they already know how to synthetically combine both for - high end chips.
As for greasy graphene or carbon graphene ?
Based on video in post.
I would say... thin coatings applied to membrains are achievable.
A junior could mulch their graphite into nano particulate size and voila !
= Graphene powder ( it's what i would do )
Then... test variuos mediums inwhich to apply, adhere the graphene powder.
Such as membranes.
Asking scientists to frabricate a single layer of greasy graphene - lol
= deterent while clever ones went on a graphite / silica buying spree with CO2 twist.
. ( own opinion )
Crystaline graphite has platlete layers
So does Clay which does filter water. Takes longer, but doable if clay is not too thick.
Pertains to, porosity, permability, saturation.
Thin crystaline graphite ( platlete * ) several layers woudld act the same.
Carbon allowing the porosity, silica platlete stacked like bricks ( full, half, full etc )
Slow permability allowing carbon to filter, steralize, remove bacteria
while silica platletes provides strength
Trick ?
Small enough to ballpark water molecule size.
That would be single layer.
I wouldn't waste time on single layer graphene or chip.
Multi layer increases odds of purification ( stacked layers - carbon, platlete, carbon etc )
More graphene + silica handles more energy, electrons, processing )
Exact opposite to the carrot and stick challenge - single layer.
I'm surprized how many scientists have and are still trying to achieve single layer.
lol
More Graphene ?

Should a junior ( nanoize ) their graphite make nano graphene ?
Wouldn't hurt.
All carbon comes into play.
That's my take.
Take it, keep it... throw it away.
Research wouldn't be complete if i didn't cover graphene.
Cheers...
