Pure solvent permeance of the functionalized boron nitride membranes. a The plot of the solvent filtration ability versus the viscosity of different solvents (EG is ethylene glycol) through FBN-0.4, and b the effect of the membrane thickness on the filtration. c The water permeation performance of the FBN-0.4 and FBN-2 membranes with 30 periodic operations of water filtration, and d the Arrhenius plot of the water permeation rate (ln k) versus inverse temperature (1000/T) for FBN-2
