The paper discussed high-performance metal cleaning using liquid carbon dioxide (CO2) and novel surfactants. There has been a major breakthrough in develoing a CO2-compatible surfactant chemistry. Research to polymerize hydrocarbon monomers in scCO2 led to the development of a group of unique CO2-compatible phillic surfactants. The key to both polymerization and surface cleaning is the surfactant used which adds functionality and enhances the efficiency of the solvent.
