离子液体(ILs)具有难挥发、热稳定、宽液程和高电导率等独特优点,在聚合物领域中的应用受到越来越多的关注。由于ILs内部的复杂相互作用力,ILs的溶剂化能力还不能像分子溶剂那样有定量的方法来表征,特别是ILs与聚合物的相容性没有一个统一的判据。本文从咪唑基ILs内部的四个主要相互作用力出发,简述了ILs内部的相互作用对不同类型聚合物在咪唑基ILs中溶解情况的影响,给读者一个初步的规律性认识。
Ionic liquids (ILs) have unique advantages such as less volatility, thermal stability, wide liquid flow and high electrical conductivity. Their applications in the polymer field are receiving more and more attention. Due to the complex interaction forces within ILs, the solvating ability of ILs can not be quantified as quantitatively as molecular solvents. In particular, there is no uniform criterion for the compatibility of ILs with polymers. In this paper, starting from the four major intermolecular forces within the imidazolyl ILs, we briefly describe the effect of the interplay between ILs on the solubilities of different types of imidazolium-based ILs and give the reader a preliminary understanding of the regularity.
