Making the composite is straightforward: graphite flakes are simply dispersed in NFC at room temperature in water to create a thick slurry. This slurry can then be printed in large areas and dried to produce a material with remarkable physical properties.
In standard tensile, fracture toughness, scratch, and ballistic tests, the material demonstrated remarkable results that rival steel, aluminum alloys, polyethylene composites, and even carbon fibers. The researchers recorded tensile strength up to 1 GPa, toughness up to 30 MJ/m3, and a specific strength of 794 MPa/g cm-3 thanks to the low density of both graphite and cellulose.
“Our material is not only stronger than many steels but also six times lighter than steel, yielding a specific strength higher than any existing metal or alloy (including titanium alloys),” says Hu.
Li and Hu are confident that the mechanical properties of the graphite-cellulose composite can be increased further, while reducing costs, to make it an ideal replacement for existing non-biodegradable materials.
“[This composite] could enable a paradigm shift from petroleum-based plastics to a revolutionary material with a drastically reduced carbon footprint,” they say.

What's going on ?
Seriously, what's going on.?
Why are the valuations bottomed out --------> such takes from investors.
Mason's riding the NOU ----> US train.
Focus too silent.
GEM too silent.
Junior's won't veer from the battery sector.
Sniff, Sniff ?
If they did branch into other exciting sectors....stock would go up.
So why aren't they ?
My spidey sense is in overdrive.
Several don't tap the grants ?
Suffer at suppressed valuations which spells dilution.
There's a real smart plan.
North Volt ( Quebec's supposed battery plant ) will used 50% bio graphite ?
Whose calling out the leaders in Quebec ( parliment ) for that brilliant move ?
Sniff, Sniff.
Like i've pointed out,
GEM should address the difference between
greasy high grade graphite + peer low grade graphite schist
Graphite Content
Carbon Content
Graphite with, additional carbon family + metalloid family
= Beneficial Conductors If GEM did so,
they'd most likely set a new presidence for grading graphite based on
= conductivty
