英文摘要	A series of alkylbetaine zwitterionic gemini surfactants, 1,2-bis[n-methyl-n-carboxymethyl-alkyl-ammonium]ethane (c (n) ab, n = 8, 10, 12, or 14), were synthesized by alkylation of n,n'-dimethylethylenediamine with an alkyl bromide, followed by reaction with sodium 2-bromoacetate. their solution properties were characterized by surface tension, steady-state fluorescence, and rheological measurements. surface-tension measurements showed c (n) ab had lower critical micelle concentration (cmc) and higher efficiency in lowering the surface tension than their corresponding monomeric surfactants. the logcmc of c (n) ab decreased linearly with increasing chain lengths up to 12. viscosity measurements showed only c(10)ab could enhance aqueous solution viscosity at high concentrations.
