Electron spin resonance studies, using spin probe correlation times, on the middle phase of three-phase micellar systems at optimal salinity show the development,upon standing,of a microviscosity gradient.This gradient does not appear when the system is not at optimal salinity. The existence of a middle phase is, therefore, not a sufficient condition for the gradient. The origin of the gradient is believed to be the facile interconversion of the water-continuous and the hydrocarbon-continuous middle phases...

Electron spin resonance studies, using spin probe correlation times, on the middle phase of three-phase micellar systems at optimal salinity show the development,upon standing,of a microviscosity gradient.This gradient does not appear when the system is not at optimal salinity. The existence of a middle phase is, therefore, not a sufficient condition for the gradient. The origin of the gradient is believed to be the facile interconversion of the water-continuous and the hydrocarbon-continuous middle phases at the critical point and is related to fluctuation phenomena. The observation of the micro-viscosity gradient is consistent with data from conductivity measurements.

用自旋示踪剂相关时间的电子自旋共振技术对三相胶束体系中的中间相进行了研究,证实在最佳含盐量下中间相有微粘度梯度存在,但在非最佳含盐量下中间相则无微粘度梯度。由此得出中间相存在不是梯度存在的充分条件。可以认为梯度是临界点下的一种起伏现象。在这点下,水连续和油连续两种类型的微乳状液处于平衡,并极易发生相互转变,因而重力场的作用使梯度产生。微粘度梯度的观察结果与电导测量的结果一致。

本文用电子自旋共振(ESR)波谱技术研究了不同pH值对酸性磷脂二棕榈酰磷脂酸(DPPA)脂质体相变性质的影响。结果表明:DPPA脂质体随pH值的增加其相变温度降低。通过对测试条件的选择和波谱参数的测量,TEMPO标记的DPPA脂质体在HEPES溶液中ESR谱不出现疏水峰的原因,是由于仪器分辨率不够以及自旋标记探针TEMPO在DPPA脂质体脂双层疏水相中的超精细偶合常数Ao和各向同性go因子与它们在HEPES溶液中的值相近。
