플라이애쉬 및 질산은을 이용한 복합소재의 다기능적 특성에 관한 연구

Electrospinning, as one of the nano technologies for synthesizing nanofiber, is widely used in filtration, thermal insulation, protective clothing, sensors, conducting devices, and other fields due to its simple equipment, low cost and easy manipulation. The electrospun fibers have small diameter, high porosity, excellent pore interconnectivity, large specific surface area, easy surface modification, polymer chain functionalization and other advantages. Therefore, in this study, electrospinning technology was employed to synthesize multifunctional composite nanofiber membrane(polyacrylonitrile/fly ash/polyacrylonitrile, PAN/FA/AgNO3), which has the ability to remove volatile organic compounds(VOCs) and heavy metals; moreover, the membrane also has excellent antibacterial ability. This research result provides an important reference value for broadening the application of electrospinning technology in the field of air and water filtration in the future.
