摘要：研究了工业级十六烷基三甲基氯化铵(CTAC)与水杨酸钠(NaSal)在乙二醇-水中形成胶束水溶液的黏度特性。分别考察了CTAC和NaSal浓度、乙二醇体积分数以及温度对形成胶束水溶液黏度规律的影响。结果表明,在乙二醇-水介质中,在一定NaSal浓度下,随CTAC质量浓度增大,胶束溶液的相对黏度将提高并出现最大值。乙二醇可弱化胶束结构强度,胶束溶液黏度随乙二醇含量的增加而降低。乙二醇体积分数低于15%时可形成黏度较大具有黏弹性的胶束体系;当乙二醇体积分数达到20%时,胶束水溶液黏度接近于溶剂黏度。在298 K^333 K内,CTAC与NaSal胶束溶液的黏度随温度升高而降低。
The viscosity of micelle aqueous solution formed by technical grade cetyhrimethylammonium chloride （CTAC） and sodium salieylate （NaSal） in ethylene glycol （EG） and water was investigated. The effects of the concentration of CTAC and NaSal,volume fraction of EG as well as the temperature on viscosity of mieelle aqueous solution were examined. The results showed that the relative viscosity of micelle aqueous solution increases and reaches a maximum value with increase of the concentration of CTAC in an aqueous mixture of EG at certain constant concentration of NaSal. EG may weaken the strength of micelle structure. The viscosity of micelle aqueous solution decreases with the increase of EG content. A micelle system with rather high viscosity and notable viscoelasticity may be formed when the volume fraction of EG is under 15%, and the viscosity of micelle aqueous solution will achieve near to the viscosity of solvent when the volume fraction of EG reaches 20%. When the temperature ranges from 298 K to 333 K, the viscosity of micelle aqueous solution formed by CTAC and NaSal decreases with the increase of temperature.
