Fig. 4: DLT mechanism of PHT-X Janus fiber membranes.
From: Biomimetic Janus membrane with spongy channels for directional liquid transport
a Water droplet on the hydrophobic TPU2 layer permeating through the conductive PHT-2. b Water droplets on the hydrophilic PAN layer diffusing through the layer. c Antigravity water transport through the PHT-2, where the water moves upward from the hydrophobic layer at the bottom to the hydrophilic layer at the top in hydrophilic-to-hydrophobic mode.
