【摘要】 利用SiO2纳米颗粒与阳离子表面活性剂十六烷基二甲基乙基溴化铵协同稳定C/W乳液,研究表面活性剂浓度对乳液稳定性的影响。随着表面活性剂浓度的增加,乳液稳定时间先增加后降低,然后趋于稳定。在纳米颗粒存在的情况下,乳液的稳定性随温度的变化较小,乳液稳定性提高,说明纳米颗粒与表面活性剂协同构建的乳液具有较好的稳定性与热稳定性。
【Abstract】 In this paper,silica nanoparticles were used with hexadecyl dimethyl ethyl ammonium bromide to stabilize C/W emulsion,and the effect of surfactant concentration on emulsion stability was investigated.As the concentration of the surfactant increased,the emulsion stabilization time increased first and then decreased,and then reached a plateau value.In the presence of nanoparticles,the stability of the emulsion changed little with temperature,and the stability of the emulsion increased,indicating that the emulsion stabilized by silica nanoparticles and surfactant had good stability and thermal stability.
