While the analysis of df provides a qualitative description of the general heterogeneity of the electrode microstructure, a quantitative description of the local environment of each particle over the simulation domain is sought. Various pair-wise radial distribution functions were computed for the systems under inquiry. The primary peak in the pair-wise radial distribution function further reinforces our inferences from the local variance in the df graph. Fig. (i) illustrates a decreasing intensity in the primary peak with a decrease in water content. This reinforces the observation of a relative decrease in ionomer solvation energy with increasing IPA content. As a result, the ionomer particles are better dispersed in solution, forming smaller primary aggregates. Meanwhile, as we approach the system's length scales, the g(r) oscillates around unity; eventually converging to it, which is typical of solvation structures observed in ideal fluids. However, an attempt to interpret the secondary structure of the g(r) is confounded by the superposition of carboncarbon, carbonionomer and ionomerionomer pair-wise functions, all contributing to the set of peaks between 40 and 150 nm.
