In Fig. we observe the variation in the aggregation of ionomer and carbon upon varying the water : IPA ratio. These structural images were obtained by the visualisation of postequilibration position data using the OVITO scripting interface . Between Fig. (i) and (v) we observe a distinct trend in the decreasing ionomer domain size, as the ionomer and carbon form an equally dispersed network. This qualitative observation was further substantiated and reinforced by the use of rigorous spatial descriptors after drying.
