After the click reaction of the SCL micelles and azide-terminus PNIPAM homopolymer, the novel PNIPAM-functionalized SCL micelles with pH-responsive cores and outer thermosensitive coronas were prepared, which was investigated act as excellent candidate of nanosized drug delivery vehicles. Finally, two types of novel shell cross-linked micelles in aqueous solution were prepared from these remarkable PMEO_2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymers by cross-linking the inner P(DMA-co-QDMA) shell of micelles upon the addition of diazide tetra derivative in the presence of copper catalyst using click chemistry.

另外，还可以使用溴丙炔对ATRP聚合出的PMEO_2MA-b-PDMA-b-PDEA三嵌段的中间PDMA嵌段进行部分季胺化，这样可以利用两端叠氮化的四甘醇来交联由PMEO_2MA-b-PDMA-b-PDEA在不同条件下形成的两种分别以PMEO_2MA或PDEA为核的胶束，从而实现了从同一个聚合物直接在水溶液中得到两种内核不同敏感的壳交联胶束。

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.

运用动态光散射和紫外分光光度计研究了两亲性嵌段共聚物自组装胶束的粒径及其影响因素，结果表明，自组装胶束的形成机理受制备方式的控制，胶束的粒径随着共聚物相对分子质量或疏水嵌段相对分子质量和有机相中共聚物浓度的增大而增大，随着有机溶剂的水溶性的增强而减小；采用透射电镜观察胶束的形态结构，发现胶束呈具有核壳结构的均匀球形；采用芘荧光探针法测两亲性嵌段共聚物的临界聚集浓度；通过降解过程中共聚物特性粘度的变化研究两亲性共聚物的降解性能，发现与PELLA和PEDLLA的相比，PECL 降解速率较慢；随着共聚物中疏水嵌段含量的增大，纳米分散液的稳定性逐渐下降；PEG含量高的PEDLLA纳米分散液随着温度的升高，纳米分散液的粘度先下降然后增大，反之，没有规律性，且随着电解质Na 2SO 4浓度的增大，体系粘度增大。

The results show that the decay of retinol and retinyl acetate are much faster in anionic micelles than that in cationic micelles and neutral micelles(TX-100), which indicate that the decay is carried out by the protonation of retinol or retinyl acetate first, then one molecular water or acetic acid is lost to produce the carbonium ion, which release the proton followed to generate the anhydroretinol.

数据显示，维生素A及其乙酸酯在阴离子胶束溶液SDS中的衰变速度要远大于在阳离子胶束溶液CTAB和中性胶束溶液TX-100中的衰变速度。

micelles：微团

脂类不溶于水,必须在小肠经胆汁中胆汁酸盐的作用,乳化并分散成细小的微团(micelles)后,才能被消化酶消化. 胰液及胆汁均分泌入十二指肠,因此小肠上段是脂类消化的主要场所. 胆汁酸盐是较强的乳化剂,能降低油与水相之间的界面张力,

micelles：微胞

在水溶液中,接口活性剂会自己组织排列成一个叫做微胞(micelles)的凝集结构. 在自然界及日常生活的应用中常常可以看到这种接口活性剂在溶液中自我组装的情况. 最近这种接口活性剂自我组装的概念更被应用来设计及控制奈米级的繁复结构.

micelles：胶束

为了进一步探讨铂的成长机制,研究人员将紫质光催化剂加在胶束(micelles)和脂质体(liposomes)上,当催化剂加在胶束上,铂原子会在胶束周围形成球形树突状奈米结构,它的直径为6到200奈米,
