▎ 摘　　要

NOVELTY - Preparing hollow fiber humidification membrane involves mixing polymers, two-dimensional nanosheets, hydrophilic additives, antibacterial materials and polar organic solvents to obtain a spinning solution. The two-dimensional nanosheet contains hydrophilic functional groups. The dry-wet phase inversion method is used, the spinning solution is extruded from the nozzle, and the core liquid is passed into the insertion tube of the nozzle simultaneously, and spinned and drawn are performed in turn to obtain a nascent hollow fiber membrane. The nascent hollow fiber membrane is gel-solidified, and obtained a hollow fiber humidification membrane. USE - Method for preparing hollow fiber humidification membrane for fuel cell humidification system (claimed). ADVANTAGE - The hollow fiber humidifying film has high water permeability, antibacterial property, gas barrier property, high strength and high temperature resistance, and is suitable for fuel cell humidification system. The raw material cost is low, and the method is simple and low cost.
