Perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) are one of the most prominent fluorosurfactants and these compounds have the most widely applications. However, such fluorocarbon surfactants have been listed as one of the most difficult to degrade organic pollutants in nature. Perfluoro-2-methyl-2-pentene was used as starting material to introducing fluorinated branch for synthesizing non-bioaccumulable alternatives. Fluorinated surfactants containing CF3CF2CF2C(CF3)2 group were successfully synthesized. The surface tension tests showed the hydrophilic groups have a great influence on the surface properties in aqueous solution, and the compound showed the best surface activities when the hydrophilic group was ammonium oxide. The length of the linking group and the size of the hydrophilic group have a general effect on the surface activity, but increasing the rigidity of the two groups can effectively increase the surface activity. The carbonyl group in the surfactant compound and the positively charged nitrogen atom will produce intramolecular interactions, enhance the rigidity of the molecule, and thus increase the surface activity. The critical micelle concentration (cmc) value of the fluorinated surfactant with ammonium oxide as headgroup was about 1.73×10-2 mol/L and the surface tension in water was 19.93 mN/m at the cmc. A excellent synergism was found when it was mixed with APG0810, the use of fluorocarbon surfactant can be reduced by a factor of 100, whereas the surface tension is basically unchanged.
