| Abstract
| - Heating-induced micelle to vesicle transition (MVT), which has been rarely reported in surfactant systems,was systemically studied in a number of mixed cationic−anionic surfactant systems. According to the turbiditymeasurements, the investigated systems can be divided into two classes: Class A and B. Heating-inducedMVT was observed in Class A at certain total surfactant concentrations and mixed surfactant ratios, while nosuch transition was found in Class B. Further investigations revealed that the heating-induced MVT is morelikely to take place in the cationic−anionic surfactant systems with relatively stronger molecule interactionand larger micelle aggregation number. The effects of several physicochemical factors, such as the variationof mixed surfactant ratios and the addition of n-decanol on the heating-induced MVT, were also studied.
