文摘
- •
Supercritical CO2 molecules prefer to accumulate at water–oil interface.
- •
CO2 accumulation leads to changes in the orientation of oil molecules.
- •
Driving force of CO2 accumulation is the water–oil interfacial tension difference.
- •
Comparable interactions of water–CO2 and oil–CO2 cause interfacial tension reduction.
