The study focuses on the synthesis and evaluation of three novel fluorinated cationic surfactants derived from hexafluoropropylene dimer. These surfactants, characterized by branched short fluorinated tails and ammonium oxide polar groups, were found to possess excellent surface properties, reducing the surface tension of water to below 20.00 mN/m at their critical micelle concentrations (CMC). The study also explored the surfactants' compatibility when mixed with other types of surfactants, such as SDS, AOS, APG, and LAB, which are commonly used in fire-fighting foams. The combination of these novel fluorinated surfactants with hydrocarbon surfactants resulted in even lower CMC and surface tension values, suggesting their potential as sustainable alternatives to perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in the formulation of aqueous film-forming foams (AFFFs) for firefighting applications. The research was supported by the National Natural Science Foundation of China and the Science and Technology Commission of Shanghai Municipality.
