This di↵erence is expected to exert a substantial influence on the overall structure of the DES. For this purpose, we classify the molecules using Voronoi tessellation, distinguishing between ChCl molecules on one side and LA molecules on the other. The time evolution of ChCl cluster counts during the MD simulation is shown in the upper panel of Figure . The behavior of this parameter exhibits noteworthy distinctions between di↵erent FF versions considered. For FF1, convergence is rapidly achieved, showing a consistent formation of approximately four clusters across various ChCl:LA ra- tios. With FF2, a similar amount of ChCl cluster formation is observed, albeit with a slight increase as the LA molecule ratio rises. Notably, FF3 presents the most distinct scenario: the number of clusters varies significantly among di↵erent ChCl:LA ratios, reaching its largest value at approximately 36 ChCl clusters for the 1:10 DES ratio.
