Based on the cation distributions in different regions of the multiparticle systems for all the cases considered (Figure and SI, Section S5.6), we infer that the anion-cation electrostatic interactions play a dominant role in localizing the cations near the surface and influencing the ionic conductivities. Based on such findings, we hypothesized that an increase in the fraction of dissociated cations would promote solvent-mediated cation transport and increase the overall conductivity. Such enhanced dissociation can be realized in practice by employing solvent hosts with higher polarities. To test our hypothesis, we considered a system of model oligomeric solvent and nanoparticle-tethered polymeric chains with polarity µ = 2 µ EO . In this context, we also studied the influence of the cation size while keeping σ anion = 2.0 σ.
