摘要

Liquid desiccant air-conditioning system has received increasing attention due to the urgent demand for humidity control and antibacterial in today's medical environment. In this system, the main parameters affecting the dehumidification performance are the specific surface area, hydrophilicity and wettability of the packing material, and the nanofiber membrane has those characteristics. Here, polyacrylonitrile/lithium chloride nanofiber membrane was fabricated by electrospinning with island nozzle. The nanofiber membrane had the dehumidification capacity with moisture absorption of 3.72 g/g. Simultaneously, the antibacterial rate against Escherichia coli and Staphylococcus aureus was higher than 99%, which satisfied the specifications for air purification antibacterial materials in the medical and health sectors (GB/T 18801-2015). More importantly, the weight per unit time and the thickness per unit area of the nanofiber membrane fabricated with island nozzle were 2.4 times and 3.4 times of those fabricated with single nozzle, respectively, indicating that the preparation efficiency was significantly improved, which provided a scheme for the rapid formation of nanofiber membranes.
