Hybrid Surfactants Containing Separate Hydrocarbon and Fluorocarbon Chains

Article abstract of DOI:10.1021/j100195a038

Two homologous series of double-tail hybrid surfactants containing a hydrocarbon chain and a fluorocarbon chain attached to the same hydrophilic head group have been synthesized.The micellar solutions of such hybrid surfactants have been studied by conductance, surface tension. (19)F NMR.The dependence of the cmc on the chain length follows Kleven's equation.The micellar aggregation numbers are 10-35 and become smaller as the chain length increases.When the hydrocarbon chain bears three carbons or more, both the fluorocarbon and the hydrocarbon chains are incorporated inside micelle.
