Producing composite nanofibrous membrane and characterization of its air permeability

Abstract

In this work activated carbon-polyacrylonitrile composite nanofibers are successfully produced by a one step, single nozzle electrospinning method. Surface morphology of composite nanofibers containing different amount of activated carbon nanoparticles is analyzed as a function of activated carbon concentration in the spinning solution. The results reveal that with increasing activated carbon concentration in the polymer solution the mean diameter of nanofibers increases and the nanofibers become less homogenous. Investigating the chemical structure and crystal structure of the resulted composite nanofibers by X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy, showed that characteristic changes happen with introducing active carbon nanoparticles into polymeric matrix. Due to the great potential of the resulted composite nanofibrous web to apply as a filter media in the face masks, air permeability is an important property that is investigated through air permeability tests.
