Abstract: The aggregation behavior of ionic liquids into micelle was studied.It was found that the micellization of ionic liquids was governed by its side-chain length, head structure and anion species, which could be promoted by increasing hydrophobicity, such as a long side-chain length, a hydrophobic anion or C2-methylated head.The side-chain length played the most active role in comparison with head group and anion.The micellization of ionic liquids would be weakened with increasing temperature.
摘要: 研究了离子液体在水相中的自聚规律,从侧链、头部及阴离子类型等方面比较了影响胶团聚集的主要因素.实验发现,增加侧链长度有利于胶团形成,降低阴离子水合性以及采用甲基化头部也利于形成胶团,碳链长度变化的作用最明显,升高温度不利于离子液体形成胶团.
