| 摘 要： | 中碳醇与高浓度的离子型表面活性剂(15%～30%)混合可制备O/W型微乳,分散质点为0.01～0.1μm。以高碳醇与低浓度离子型表面活性剂(0.6%～3%)为混合乳化剂,可制得内相体积为25%的苯乙烯在水中的微小乳状液(miniemulsion)粒子大小为0.1～0.4μm,与普通乳状液相比,具有颗粒小、分散均匀、稳定性高的特点。本文研究季胺盐等离子型表面活性剂与高碳醇混合乳化剂体系中制备微小乳状液的条件及其稳定机制。

| Abstract: | The stable oil-in-water miniemulsion were prepared using mixed emulsifier comprising a mixture of ionic surfactants (quaternaryammonium compounds) and long chain fatty alcohols (C_8 to C_(16)) in low concentration. The chain length of the fatty alcohols, mole ratio of surfactant to fatty alcohol appeared an important factor influencing the formation of miniemulsions. The temperature of emulsification, property of oil phase and volume fraction of internal phase also affected the oil droplet size and the stability of the emulsion. The stabilization of emulsions has been interpreted in terms of the formation of the lyotropic liquid crystals. |
