摘要：

The spreading isotherms of DODAC at the water-air interface were determined as a function of temperature. We verified that a study of the spreading film is the starting point for a better understanding of the most suitable conditions to obtain more complex aggregates, such as Langmuir-Blodgett (LB) films or vesicles. When the DODAC monolayer was in a liquid-condensed phase, this resulted in the optimum conditions for obtaining LB multilayers. In contrast, when the monolayer was in a liquid-expanded phase, multi- and unilamellar vesicles were obtained after sonication. Vesicles were also obtained when the system was below the gel-liquid crystal transition temperature (T(c) = 37-degrees-C), but a greater fraction of multilamellar vesicles were formed, as indicated by turbidimetric data.
