Objective: To discuss the influences of the concentrations of sodium cholate, cholesterol and drug, preparation temperature, ultrasonic time and power on the particle size and encapsulation efficiency of Flos Magnoliae volatile oil nano-liposome through film-ultrasonic wave technique together with membrane filter method.

目的：采用薄膜分散-超声-膜过滤法制备辛夷挥发油纳米脂质体，考察胆酸钠、胆固醇、药物浓度、超声功率和超声时间等因素对辛夷挥发油纳米脂质体粒径及包封率的影响，并对纳米脂质体的形貌、稳定性进行分析。

Compared with the conventionalemulsion polymerization system in the presence of sodium dodecyl benzene sulfonate, the latices prepared by emulsifier-free emulsion polymerization have much more narrow distribution of latex particle sizes (0.2um in diameter), better resistance to electrolytes, pH, freeze-thaw, and better mechanical stability. Not only the tensile strength of the copolymers prepared by this method is obviously increased, but also the water resistance and adhesion capacity are significantly enhanced. On the other hand, the TG results indicate the copolymer has lower thermal stability than conventional copolymer.
