Separation properties of STRIPS bijel-derived membranes. a Flux of pure water as a function of transmembrane pressure for membranes polymerized 5 cm from the nozzle with different silica nanoparticle fractions (40 mM CTAB, 0% EtOH in continuous phase). b Hydraulic permeability (i.e., slope of lines in a) as a function of silica nanoparticle concentration for membranes polymerized at distances of 5 cm (blue points) and 30 cm (green points) from the extrusion nozzle (both 40 mM CTAB, 0% EtOH in continuous phase, curves are drawn to guide the eye). The inset shows photographs of a suspension of citrate stabilized gold nanoparticles before (feed, 0.01 wt% 20 nm Ag particles at pH 8) and after (filtrate) flowing through the membrane fabricated with 0.35 g_silica/g_{dry fiber}, 40 mM CTAB, polymerized at 30 cm distance from the nozzle. UV Vis spectra of the feed and permeate solutions are provided in Supplementary Fig. 1
