Transition state theory unveils enthalpy–entropy interplay in polyamide nanocomposite membranes for enhanced water–salt selectivity

Key Points

• Enhanced water-salt selectivity achieved through better enthalpy-entropy interplay in membranes, leading to significant performance improvements.
• Key evidence shows a notable increase in selectivity metrics, with changes linked to polyamide structure modifications and material composition.
• Analysis employs transition state theory to delineate the contributions of enthalpy and entropy, clarifying their roles in the membrane mechanisms.
• Findings highlight the potential for polyamide nanocomposite membranes; broader applications could enhance water purification technologies.
