Exploring the Dynamics and Structure of Soft Colloids at Oil-water Interfaces
自一百年前,膠體粒子於界面上的自發吸附被發現了後,它們穩定乳液的物理現象已經被研究了好一段長時間。這一類以固體微粒為穏定劑的乳液稱為皮克林乳液(Pickering Emulsion)。因為固體微粒在界面上的吸附能量非常高,使這一類乳液比起小分子乳化劑穏定的乳液有著一些有趣的差異。例如更高的穏定性和可以排除使用小分子乳化劑的一些不良效果。 === 在近幾年,科學家們的興趣都落在運用亞微米大小的聚N-異丙基丙烯酰胺(pNIPAM)水凝膠來穏定皮克林乳液。這些水凝膠可以來界面上變形,而且導致界面出現特別的特質和影響了粒子的排列結構。界面的張力和流變性質都會因而有所改變。而且,pNIPAM水凝膠的響應...
