摘　　要：研究了十二烷基三甲基己酸铵(C_(12)NC_6)与十二烷基苯磺酸钠(SDBS)复配体系的表面活性及应用性能。结果表明,复配体系的临界胶束浓度(cmc)和临界胶束浓度下的表面张力(γcmc)均比单一表面活性剂的低,其扩散吸附速率较单一表面活性剂的慢;复配体系中SDBS的加入可提高C_(12)NC_6的稳泡性、润湿性;当n(C_(12)NC_6):n(SDBS)=1:1时,复配体系的cmc和γcmc达到最低,具有较好的稳泡性和润湿性,但发泡性和乳化性变差。Surface activities and application performances of dodecyhrimethylammonium hexanoate （C12NC6） and sodium dodecyl benzene sulfonate （SDBS） blend systems were measured. Results show that the critical mieelle concentration and surface tension of the blend systems are lower than each single component surfactant of the system; and the rate of diffusion adsorption of the blend systems is slower than that of each single component surfactant. The foam stability and wetting power of C12NC6 are improved by the addition of SDBS. As n（C12NC6）： n（SDBS） = 1：1, the critical micelle concentration and surface tension of the blend system achieve the lowest value, and the blend system displays better foam stability and wetting power, but the foaming power and emulsifying power of the blend system become worse.
