Table 2 Membrane characteristics

From: Membrane condenser as emerging technology for water recovery and gas pre-treatment: current status and perspectives

Material property -hydrophobic
-resistant to alcohols, acids and surfactants
Morphology Porous, symmetric or asymmetric or composite
Thickness 20–100 μm
Porosity 70–80%
Thermal conductivity high
Materials - Polymers (e.g., polypropylene, poly-vinylidenefluoride, poly-tetrafluoroethylene, Hyflon AD (2,2,4-trifluoro-5-tri-fluorometoxy-1,3-dioxole), ECTFE (Ethylene-Chlorotrifluoroethlyene copolymer), etc.)-
Modified hydrophobic ceramic membranes (e.g., by coating hydrophobic polymethylsilsesquioxane aerogels on alumina membrane supports, by applying fluoroalkylsilanes hydrophobic agent on alumina hollow fibers)
-mixed matrix (e.g., fillers of graphene, zeolite, carbon nanotubes, etc.)
Configuration Flat, hollow fiber, tubular
