准单扩散的“平头”聚苯乙稀-聚丙稀酸（PS-b-PAA）胶束

指出选择某种准单单一的“平头”聚苯丁二烯-聚亚克力（PS-b-PAA）胶束，采用摸拟探索腐殖酸（HA）固体与铀酰的充分功效。因其X电子束对血本属的的敏理性，核心使用的导入散发XX射线小角散射（SAXS）的技术分析方法了铀酰对PS-b-PAA胶束空间结构特征的危害，样品管理的散射曲线美更具比较突出的球壳空间结构特征振荡器器峰，粘附铀酰后，振荡器器峰硬度扩大，直接显示低q区域划分的散射抗压强度增添。球壳仿真模型线性拟合分折表述：弱碱性水盐溶液中，铀酰促使PAA壳层板厚降低了、衬度多；平均的1个PS(279)-b-PAA(69)胶束可吸附性600个铀酰铝离子[UO22+, UO2OH+,(UO2)2(OH)22+]；由于铀酰溶度的添加，胶束出现探亲签证，以求引发乳浊液。

Figure 1. SAXS curves obtained from PS-b-PAA micelles in H2O andDMF/H2O solutions; the curves are shifted vertically by factors of 2 and 4 for clarity; black lines are the best fits to core-shell model (a). Modelfitting to the SAXS data of PS-b-PAAmicelles in H2O; the solid, dash, and dash dot lines denote the fitsto core-shell, solid sphere, and spherical shell models, respectively (b).

Figure 2. SAXS curves obtained from the PS-b-PAA micelles and uranyl nitrate mixtures; the curves are shiftedvertically by factors of 2, 4, and 8 for clarity; black lines black lines arethe best fits to core-shell model (a). A zoom-in of (a) in the medium q range (b). Deviation between the experimental andfitted data at the low q region (c). Notethat PS-b-PAA-7UO2 and PS-b-PAA-10UO2 sample are notevaluated because they show precipitations.
