Supercritical CO2 as a Green Solvent for Polymer Processing
Quick fact
Supercritical carbon dioxide (scCO₂) can tune its solvent strength from gas-like to liquid-like simply by adjusting pressure and temperature, allowing it to dissolve many polymers that are insoluble in ordinary CO₂ gas or liquid.
Why this is interesting
You know how dry cleaning uses harsh chemicals? What if we could 'dissolve' polymers using the same gas that puts the fizz in your soda?
