  Synthesis and properties of gemini-type hydrocarbon–fluorocarbon hybrid surfactants

  摘要：

  Gemini-type hybrid surfactants with two fluorocarbon chains connected through a hydrocarbon spacer, F(CF2)(m)(CH2)(2)CH(OSO3Na)(CH2)(n)CH(OSO3Na)(CH2)(2)(CF2)(m)F [Fm(Hn)FmOS, m = 4, 6; n = 5,6,7, 8)], were synthesized and their surface chemical properties were examined with the aim to have highly functional and highly water-soluble fluorinated surfactants when compared with the conventional fluorinated surfactants. Comparisons of the surface chemical properties of the synthesized gemini-type hybrid surfactants with those of monounit-type hybrid surfactants, F(CF2)(m)(CH2)(2)CH(OSO3Na)(CH2)(n)H [FmEHnOS, m = 4, 6: n = 3, 5)], revealed that gemination causes a remarkable lowering (about 1/100) in cmc value while it produces little changes in Krafft point (below 0 degrees C)and surface tension at cmc (gamma(cmc)).
