a Water permeance of t-TFX compared to e-TFX, i-TFX, hand-cast PSU-TFC, and commercial HPRO. b Observed rejection and salt permeability of t-TFX compared to other counterparts. c Normalized water permeance of TFX membranes versus hand-cast PSU-TFC and commercial HPRO. d Active layer crosslinking degree of TFX membranes, hand-cast PSU-TFC, and commercial HPRO. e Schematic of enhanced mechanical strength and stability of the TFX composite membrane by turning thermoplastic into thermoset. f Schematic illustration of adapting existing TFC membrane manufacturing lines for roll-to-roll production of TFX membranes. Water permeance is presented in LMH/bar (Liter m−2 h−1 bar−1). Solute permeability is presented in LMH (Liter m−2 h−1). Data represent the mean ± standard deviation from three independent experiments, where applicable.
