Аннотация:
Ionic liquids containing macromolecules as solutes are of considerable interest for polymer materials science. However, these systems are at an early stage of investigation. In this study, the structural features of ionic liquids containing flexible polymer chains under good solubility conditions are investigated on the basis of the polymer integral equation method. The structural properties of the system are analyzed in reciprocal space by using partial structure factors. In the presence of attractive interaction between the polymer chains and polar cationic groups, there is a range of polymer concentrations at which the long-range correlations of polymer chains are observed. When these correlations are pronounced and the polymer chain size is much larger than the correlation length of pure ionic liquid, the decrease of the characteristic scale of the long-range polymer ordering with increasing polymer concentration fits the power dependence. The effect of such an increase on the ordering of the ions of the solvent is also considered. © 2010 American Chemical Society.
