摘要：

The spreading kinetics of dimyristoylphosphatidylcholine liposomes at the air/water interface, below and above the main phase-transition temperature are studied by measuring the evolution of the surface pressure. The reorganization mechanism of the closed liposomal bilayers into a surface film is dependent on the state of the bilayer. The estimated values of the interfacial reorganization rate constant for liposomes in a liquid-crystal state are larger than those for liposomes in crystal-gel state. Atomic force microscopic imaging demonstrates the different morphology of the interfacial mesophases obtained.
