Abstract:

Supercritical carbon dioxide microemulsion has become a new research direction in the field of green chemistry in recent years. It combines the advantages of supercritical fluid and microemulsion. Owing to its stable thermal properties,tunable physical and chemical properties as well as the designable structures,supercritical carbon dioxide microemulsion has a wide application prospects in chemical reaction,material preparation,extraction,separation and other fields. In order to understand the mechanism of thermodynamic properties, phase behavior and the interactions among the components of this complex system,this article summaries the applications of molecular simulation technology in the field of supercritical carbon dioxide microemulsion as well as binary systems of ionic liquids/H₂O and ionic liquids/CO₂. A systematic review including force field, ensemble choices, parallel computing,self-assembly mechanism and other aspects were given herein. Finally, a new direction on supercritical carbon dioxide domaining ionic liquids microemulsion and the advantages of molecular dynamics simulation in dealing with supercritical carbon dioxide microemulsion system were proposed.
