Definition
The structure heterogeneity in ionic liquids is the nanoscale spatial segregation of polar and nonpolar domains resulting from the assembly of alkyl chains of cations or anions due to the interplay between van der Waals of nonpolar chains and electrostatic interactions of polar heads.
Introduction
The nanoscale spatial aggregation is commonly observed in ionic liquids (ILs) with long alkyl chains, which can further affect the chemical, thermophysical, and physiochemical properties of ILs. Therefore, exploring the structure heterogeneity in ILs is critical for understanding phenomena resulting from the nanoscale aggregation of ILs. Experimental measurement techniques including small/wide-angle X-ray scattering (S/WAXS), small-angle neutron scattering (SANS), and X-ray diffraction (XRD) as well as molecular dynamics (MD) simulation have been implemented to investigate the impacts of alkyl chain length...
