Abstract

Many phenomena take place during different types of emulsion inversions, particularly a change in interface curvature and drop size, which could be detected by backward light scattering. Monitoring the backscattering signal allows us to detect the emulsion inversion in three main cases, one transitional and two catastrophic types. The backscattering data could give some clue as to emulsion morphology, which is not available from conductivity measurements.

摘要

在不同类型的乳液转相过程中会发生许多现象，特别是界面曲率和液滴尺寸的变化，这些变化可以通过后向光散射检测到。监测后向散射信号使我们能够在三种主要情况下检测乳液转相，一种是过渡型，两种是突变型。后向散射数据可以提供一些有关乳液形态的线索，而电导率测量无法获得这些信息。
