摘要: Typical cationic and anionic surfactants were chosen and their interactions were calculated
by quantum ular pairs with fluocarbon and hydrocarbon chain: C4H10/C5H12, C4F10/C5H12, and
C4F10 /C5F12, respectively.When hydrophilic group with cationic and anionicions is
introduced, interaction energies are -287.40kJ.mol-1,-311.18 kJ.mol-1 and -345.83 kJ.mol-1.
The results show that there is strong static interaction between cationic and anionic
surfactants. It has been predicted that mixed monolayer may be formed and surface activity
is enhanced favorably, especially for mixtures of cationic and anionic surfactants with
fluocarbon and hydrocarbon chains. The anionic surfactants, sodium
octadecylbenzenesulfonate perfluopolyetherbenzenesulonate(ANF-Ⅰ) was synthesized, mixture
effects of ANF-Ⅰ with sodium octadecylbenzenesulfonate or dodecyldimethyl benzylammonium
bromide were studied. The results indicate that the efficiency of mixing increased and the
theoretical prediction was testified. These results can provide useful information for the
design of new surfactants.
