  • Composite nanofiber membranes of thermoplastic urethane/polyacrylonitrile (TPU/PAN) were prepared by an improved electrospinning technique, and the influence of different composite modes and layers on the microstructure of the composite nanaofiber membrane was investigated. Meanwhile, the influence of surface density of nanofiber membrane on the filtration efficiency and filtration pressure drop was also explored in the air filtration test. In order to obtain nanofiber membranes with the high efficiency and low resistance for air filtration, the effect of composite modes and layers of TPU (crude fiber) and PAN (fine fiber) on air filtration were demonstrated. The results show that the optimal combination mode between TPU and PAN is Mixed/PAN, and the optimal number of layers is Mixed/PAN/Mixed/PAN. The best air filtration was achieved when the surface density was 1.31 g·m-2, and the filtration efficiency reached 97.34%, the filtration pressure drop was only 98.13 Pa, and the quality factor was 0.038 pa-1. This indicates that the higher efficiency and the lower resistance can be achieved by combination of composite modes and layers. At the same time, the pore diameter of the nanofiber membrane under the optimum conditions was tested by bubble pressure method, and the average value was 2.26 μm.

Meanwhile, the influence of surface density of nanofiber membrane on the filtration efficiency and filtration pressure drop was also explored in the air filtration test. In order to obtain nanofiber membranes with the high efficiency and low resistance for air filtration, the effect of composite modes and layers of TPU (crude fiber) and PAN (fine fiber) on air filtration were demonstrated. The results show that the optimal combination mode between TPU and PAN is Mixed/PAN, and the optimal number of layers is Mixed/PAN/Mixed/PAN. The best air filtration was achieved when the surface density was 1.31 g·m-2, and the filtration efficiency reached 97.34%, the filtration pressure drop was only 98.13 Pa, and the quality factor was 0.038 pa-1. This indicates that the higher efficiency and the lower resistance can be achieved by combination of composite modes and layers. At the same time, the pore diameter of the nanofiber membrane under the optimum conditions was tested by bubble pressure method, and the average value was 2.26 μm.
