The morphology of polymer blends, mixed micelles and drug-loaded mixed micelles was characterized by differential scanning calorimetry (DSC), X-ray diffraction, transmission electron microscopy (TEM) and polarized light microscope (PLM) methods.

• 采用溶剂浇铸法制备不同摩尔比例的MePEG-chol/MePEG-st共混物。 利用示差扫描量热法(DSC),带热台的偏光显微镜(PLM)和广角X射线衍射(WAXD)考察共混物的凝聚态。
