在这项工作中，发展了一种在室温离子液体和深共晶溶剂的混合物中掺入碳纳米管制备聚合物整体的有效方法。在二元绿色溶剂1-丁基-3-甲基咪唑四氟硼酸盐和氯化胆碱/乙二醇的辅助下，单壁碳纳米管成功地分散在预聚混合物中，而不需要对碳纳米管进行氧化切割，从而减少了挥发性有机化合物向环境中的排放。采用毛细管电色谱对新型单壁碳纳米管整体柱进行了表征。与未掺入单壁碳纳米管的整体柱相比，掺入单壁碳纳米管的整体柱具有较高的色谱柱效率(251,000个/m)。离子液体和深度共熔溶剂的混合组成可以调节整体柱的形态，使其具有良好的柱透性和良好的烷基酚和烷基苯小分子分离能力。结果表明，该方法是一种制备多功能聚合物整体的绿色策略。
In this work, an efficient method to prepare polymer monoliths with incorporated carbon nanotubes in a mixture of room temperature ionic liquid and deep eutectic solvents was developed. With assistance of the binary green solvent, 1-butyl-3-methylimidazolium tetrafluoroborate and choline chloride/ethylene glycol, single-walled carbon nanotubes were dispersed successfully in pre-polymerization mixture without need of oxidative cutting of carbon nanotubes, which may allow depletion of the emission of volatile organic compounds into environment. The novel single-walled carbon nanotubes monolith was evaluated by capillary electrochromatography. Compared with the monolith made without single-walled carbon nanotubes, the monolith with the incorporation of single-walled carbon nanotubes exhibited high column efficiency (251,000 plates/m) in the chromatographic separation. The morphology of the monolith can be tuned by the composition of mixture of ionic liquids and deep eutectic solvents to afford good column permeability and excellent separation ability for small molecules of alkyl phenones and alkyl benzenes. The results demonstrated that the method is a green strategy for the fabrication of multifunctional polymer monoliths.
