Comparison of omniphobic membranes and Janus membranes with a dense hydrophilic surface layer for robust membrane distillation

Hypercrosslinked Hydrogel Composite Membranes Targeted for Removal of Volatile Organic Compounds via Selective Solution-Diffusion in Membrane Distillation

“…The significantly increased LEP would be conducive to membrane antiwetting performance. The LEP value of the Alg/Al PTFE membrane is the equivalent of the capillary pressure in the dense Alg/Al layer (Figure E) . According to the Young–Laplace equation, the remarkable increase in LEP values can be attributed to the combination of the hydrophilic nature and the nanosized pores (Figure F) of the Alg/Al layer .…”

“…LEP serves as an important indicator to evaluate the antiwetting performance of MD membranes, which is defined as the critical pressure required for the liquid to enter the nonwetting membrane . As shown in Figure D, the PTFE membrane possessed an LEP value of 7.5 bar.…”

Interlayered Interface of a Thin Film Composite Janus Membrane for Sieving Volatile Substances in Membrane Distillation

“…As shown in Figure S14A, the Substrate (Janus) can resist oil fouling owing to its underwater oleophobic performance but be sharply wetted by the SDS surfactant, verified by the sharply increased vapor flux and distilled water conductivity. In contrast, the TFC (PP + PA) membrane can resist membrane wetting and fouling because the superhydrophilic and dense TFC skin layer can simultaneously sieve the SDS and oil droplets, schematically demonstrated in Figure S14B. , …”

Superhydrophobic Membrane Fabricated via In Situ Polymerization of Dopamine at the Air–Water Interface for Membrane Distillation with Antiscaling Performance

“…Compared with the membrane loaded with only PDA (PTFE-PDA, Figure S8), PPA exhibited a higher water flux due to the improvement in hydrophilicity. However, this was not conducive to scaling resistance …”
