Abstract
Modern instruments used to observe water at interfaces can distinguish individual molecular layers, measure dielectric permittivity within nanometer-scale gaps, and track reorientation on femtosecond timescales. Yet, a materials scientist asking whether increasing the density of ionizable groups would improve membrane performance finds little direct guidance in this literature. We attribute this disconnect to three factors: the term “structure” refers to three independent properties of water; the parameters typically controlled are not actually independent variables; and the state of water influences material performance through multiple pathways that yield opposing effects. We synthesize the accumulated evidence regarding the interdependence of five factors, show how ion-series reversal can serve as a screening indicator of conditional coupling when alternative mechanistic causes are excluded, and explain why a specific change in the state of water can enhance performance in some areas while impairing it in others. This framework has implications for the design of membranes, sorbents, and coatings and suggests that many of the most pressing challenges in the field can be addressed using existing tools, provided that greater emphasis is placed on how measurements are reported and experiments are designed rather than solely on acquiring new data.
