中文摘要：

在水中制备了β-环糊精／聚乳酸接枝共聚物（β-CD—g-PLA）胶柬。以芘为探针．采用稳态荧光法研究了胶柬的形成及临界胶束浓度（CMC）），利用动态光散射（DLS）和透射电镜（TEM）研究了胶束的粒径分布和形态．结果表明，在一定条件下接枝共聚物在水中能够形成球形的稳定胶束．CMC值和胶柬粒径随着共聚物中疏水性聚乳酸（PLA）链段含量的增加而减小．

英文摘要：

β--Cyclodextrin/poly （lactide） （β-CD-g-PLA） graft copolymer micelles were prepared in water. The fluorescence technique was used to determine the critical rnicelle concentrations （ CMC） of copol- ymer micelles. The diameter and distribution of micelles were characterized by dynamic light scattering （DLS） and its shape was observed by transmission electron microscopy （TEM） . The results showed that the round nano-micells were formed steadily by these copolymers in water. The CMC of copolymer solution and the size of micell were reduced with the increasing of the proportion of hydrophobic parts.
