图1显示了SLES、SLES/CAPB和SLES/CAPB/CCB系统的粘弹性模量(麦克斯韦型响应)。如下表所示,SLES/CAPB系统形成了长蠕虫状胶束,其轮廓长度L̅为445.8 nm,短的纠缠长度le和持久长度lp表明蠕虫状胶束的高度纠缠和灵活性。然而,sample2和sample3对比发现,加入CCB后,胶束的纠缠程度和潜在缩短似乎要弱得多。加入2%重量比...

DWS测量中我们在连续相中加入直径为980nm的示踪颗粒,所得混合物含有1.0wt.%PS颗粒。因此,PS颗粒探测与乳液的连续相相对应的环境。DWS测量在透射几何结构中厚度为L=2 mm的比色皿中进行。为了校准,使用直径为980nm的1.0wt.%PS颗粒在水中的分散体系。样品的光子传输自由程l*的测量值为398µm。
