Membrane based separation technology has been studied for various applications such as gas separation, solvent purification. Among them, membrane with high water vapor permeability is an emerging technology for air dehumidification. This membrane can reduce power consumption due to extracting water vapor from the humid air without release of latent heat. Here, We designed hydrophobic polymer based dense membrane with selective water permeability incorporated with hydrophilic additives, cellulose nanofiber (CNF). CNF provides non-ionic water vapor channel and at the same time reinforces polymer mechanical property. The structure and properties of the membrane are characterized by SEM, water-vapor permeability analysis, and gas permeation test. |
