Research progress of the surface/interfacial properties and structures of ionic liquids based on AFM/STM techniques

AFM/STM技术对于离子液体表/界面性质与结构的研究非常重要.目前,使用AFM/STM技术直接观察离子液体薄膜、离子液体混合物、负载离子液体的结构及性质以及原位观察反应过程离子液体结构及性质变化等研究不断涌现,尤其在原位观察离子液体表/界面性质与结构变化方面,AFM/STM技术得到了很好的应用.未来应主要加强离子液体不同阴阳离子结构、性质对离子液体与气体、离子液体与固体界面影响的研究,进而形成系统化的理论,为离子液体吸收气体及催化反应的应用提供理论支持,并进一步构建模型,指导离子液体的设计.

AFM/STM techniques are very important in the surface/interfacial properties and structures of ILs. At present, the research of using AFM/STM techniques to directly observe the structures and properties of ILs membrane, ILs mixtures,load lls, and the structures and properties of Ils in the reaction process by in situ observation was made. Especially in the changes of surface/interracial properties and structures of ILs by in situ observation,AFM/STM techniques got very good application. In the future, the research on ILs with different anion and cation structures, the effects of properties for ILs and gases, ILs and solid interface should be mainly strengthened, and then a system of chemical theory is cation of ILs absorbing gas and catalytic reaction, and to be formed which provides theory support for the applifurther the model is to be built to guide the design of ILs.
