Fig. 5: Oil-water separation performance of PHT-X Janus fiber membranes.
From: Biomimetic Janus membrane with spongy channels for directional liquid transport
a Underwater oil contact angle on the hydrophilic side of PHT-X Janus fiber membranes; the inset is oil droplet shape on the hydrophobic side, and all the samples had the same results. Error bars in a represent standard deviations, n = 3 independent samples. b Water collection behavior of the hydrophilic side of PHT-2 in oil. c Water rejection behavior of the hydrophobic side of PHT-2 for water in oil. d Oil-water separation device. e Separation efficiency and flux of PHT-X-Janus fiber membrane. Error bars in e represent standard deviations, n = 3 independent samples. f Separation efficiency and flux of PHT-2-Janus fiber membrane under different separation cycles. g Comparing the separation performance of the PHT-X membrane with that of the fabric/fiber membrane reported in the literature, PHT-X showed even higher throughput at a similar high separation efficiency.
