A great many works have indicated that common hydrocarbon surfactants generally can not form microemulsions in sc-CO_2,so the structure design of surfactants becomes necessary.

Surface activity and fire extinguishing performance of fluorocarbon-hydrocarbon surfactants;

Property of mixed solution of sodium dodecyl sulfate and non-ionic fluorocarbon surfactant;

Synthesis of amino acid type amphoteric fluorocarbon surfactant and its application in extinguishing agent;

Synthesis and application of fluorocarbon surfactant

It showed that counter charged hydrocarbon surfactants decrease spreading concentration of fluorocarbon surfactants and make fluorocarbon surfactants that have high surface tension spread on oil.

The reason of aqueous film forming foam (AFFF) having not been used widely in China was discussed,based on the relationship between AFFF and fluorocarbon surfactants.

Ethoxylated nonylphenol phosphate gemini surfanctants with different degree of polymerization were synthesized by using ethoxylated nonylphenol,glycol diglycidyl ether and Phosphorus oxychloride as raw materials and BF3-ethyl ether as catalyst.
