A Janus Mesh with Robust Interface and Controllable Wettability for Water Transport

Figure 1

Schematic diagram of the experimental process. CA and PVDF-HFP are first prepared as porous membranes and fibrous membranes by spin-coating and electrospinning methods, respectively. The fibrous membranes obtained by electrospinning are then combined together to form PVDF-HFP/CA composite membrane and treated with NaOH to obtain PVDF-HFP/CA Janus membranes with strong interfacial adhesion, which made them good candidates for water transport.
