| 摘 要： | Typical cationic and anionic surfactants were chosen and their interactions were calculated by quantumchemical method. Interaction energies are -0.2378kJ·mol~(-1),-3.3394kJ·mol~(-1) and 0.1204kJ·mol~(-1) for the molec-ular pairs with fluocarbon and hydrocarbon chain: C_4H_(10)/C_5H_(12), C_4F_(10)/C_5H_(12), and C_4F_(10)/C_5F_(12), respectively.When hydrophilic group with cationic and anionicions is introduced, interaction energies are -287.40kJ·mol~(-1),-311.18kJ·mol~(-1) and -345.83kJ·mol~(-1). The results show that there is strong static interaction between cationicand anionic surfactants. It has been predicted that mixed monolayer may be formed and surface activity is en-hanced favorably, especially for mixtures of cationic and anionic surfactants with fluocarbon and hydrocarbonchains. The anionic surfactants, sodium octadecylbenzenesulfonate perfluopolyetherbenzenesulonate(ANF-Ⅰ)wassynthesized, mixture effects of ANF-Ⅰ with sodium octadecylbenzenesulfonate or dodecyldimethyl benzylammonium
