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。

Two possible evolution mechanisms of a multicompartment micelle with a ring/cogwheel core are identified, large cylindrical micelle curling then closing up and disc-like micelle perforation.

不同的初始混合状态改变了混合胶束的形成路径，虽然胶束最终的大体形貌几乎没受到什么影响，但胶束的微细结构却有差异。

Being different from conventional multimolecular micelle systems, the unimolecular micelle system of P(AMC14AB) not only shows critical micellar concentration (CMC=0),(i.e.once added to pure water, the surface tension decreases immediately in spite how small the density is), but also the surface tension stays almost the same with the concentration increasing.

P(AMC14AB)在溶液表面也发生表面吸附，使水的表面张力下降，即P(AMC14AB)也具有表面活性；随着浓度增大，表面吸附量增大，水的表面张力持续下降；当表面吸附达饱和时，表面张力～浓度曲线上出现突变点，该点定义为饱和的表面吸附浓度，而不应该再称为临界胶束浓度。

micelle：胶束

虽然脂类化合物也有类似性质,但是去垢剂能够形成胶束(micelle),所以相比之下非常易于在水中溶解. 去垢剂的疏水基团一般是下面三种(1)直链或者支链烷基结构(2)类固醇之类的多元环结构(3)取代苯基结构(比如大家常用的Triton X100或者NP40).

micelle：胶团

当这些脂肪酸处于有水环境中时,它们的亲水端和疏水端都会有序地排列,当水分蒸发后,最终形成了微小的脂肪酸球体--胶团(micelle). 依靠化学浓度和环境的PH值,这些胶团可以形成分层的膜或者囊泡(vesicle). 该项研究以青藏高原特有物种高原鼠兔为研究对象,

micelle：胶粒

磷脂质分子在水中可自动排列成亲水端向外,疏水端向内的微胶粒(micelle);或者是两疏水性末端靠拢而形成外侧皆亲水的脂双层空泡,即是细胞膜的基本结构(图二).

micelle：微胞

加入有机溶剂(MeOH,EtOH,TFE)的实验中,所有溶剂皆能在一定浓度以上诱导蛋白产生α-螺旋,且Ag473-1及Ag473-3诱导出的二级结构类似;但在加入SDS给予微胞(micelle)环境,诱导出α-螺旋时,Ag473-3比 Ag473-1明显提早形成螺旋之二级结构.

neutral micelle：中性胶粒

neutral humus 中性腐殖质 | neutral micelle 中性胶粒 | neutrality point 中性点
