以阳离子三联表面活性剂双(2-羟基-二亚甲基醚)-α,ω,γ-三(十六烷基二甲基氯化铵)(Trimer C16)为主剂,水杨酸钠(NaSal)为有机反离子,氯化钠(NaCl)为无机反离子,制备了阳离子蠕虫状胶束体系。利用电导率-表观黏度法研究了Trimer C16的相行为,考察了不同有机反离子NaSal、苯甲酸钠(NaBENZ)及甲酸钠(NaFM)对Trimer C16克拉夫特温度(T k )的影响,通过动态流变手段研究了Trimer C16/NaSal/NaCl的流变行为,并采用表观黏度法考察了温度(T)及剪切时间(t s )对该体系表观黏度(ηa)的影响。结果表明:TrimerC16的临界囊泡浓度(CVC)为0.015 mmol?L?1,临界胶束浓度为0.042 mmol?L?1;三种有机反离子对TrimerC16的Tk影响大小顺序为:NaSal>NaBENZ>NaFM;剪切速率(r′)为100 s?1时, TrimerC16/NaSal/NaCl体系的黏度仍高达70 mPa·s;T=100℃时,转速为50 r?min?1下,TrimerC16/NaSal/NaCl体系的ηa为61.8 mPa?s,而同一测试条件下,相同摩尔浓度的单链表面活性剂胶束体系的ηa已接近水的黏度。TrimerC16蠕虫状胶束体系耐较高温、耐剪切且破胶彻底。/NaSal/NaCl

Wormlike micelles (WLMs) were formed in aqueous solutions of a cationic trimer surfactant di(2-hydroxyl-dimethylene ether)-α,ω,γ-triple (dimethylcetylammonium chlorine) (TrimerC16) in the presence of sodium salicylate (NaSal) and sodium chloride (NaCl). The phase behavior of TrimerC16in aqueous solutions was studied by conductivity-viscosity coupling, and the effect of different organic salts, including NaSal, sodium benzoate(NaBENZ) and sodium formate(NaFM) on the Krafft point (Tk) of TrimerC16was investigated. Moreover, the rheological behavior of the TrimerC16/NaSal/NaCl system was investigated by dynamic rheology, and the effects of temperature (T) and shearing time (ts) on the apparent viscosity(ηa) of TrimerC16/NaSal/NaCl solutions were examined by apparent viscosimetry. The results show that the critical vesicle concentration(CVC) and critical micelles concentration(CMC) of TrimerC16are 0.015 and 0.042 mmol?L?1, respectively. The ability of NaSal, NaBENZ and NaFM to decrease the Tkof TrimerC16is in the order of NaSal>NaBENZ>NaFM.ηaof the TrimerC16/NaSal/NaCl system still remains above 61.8 mPa·s under 50 r?min?1 rotation speed at 100℃, andηswas more than 70 mPa·s whenr′ achieves 100 s?1. The TrimerC16/NaSal/NaCl system has good temperature resistance, shear resistance and gel breaking ability.
