Fabrication and characterization of electrospun polyacrylonitrile (PAN) @ bamboo shoot cellulose nanowhisker (BSCNs) @ carbon nanotube (CNT) composite membrane with enhanced dye adsorption properties.

In this study, polyacrylonitrile (PAN) @ bamboo shoot shell cellulose nanowhisker (BSCN) @ carbon nanotube (CNT) electrospun composite membrane with enhanced dye adsorption performance was prepared. Methyl blue (MB) was used for dye experiment. The results showed that with the increase of BSCNs, the diameter of the nanofibers in composite membranes gradually increased. When 1.2% BSCNs was added, the removal rate of methylene blue is up to 92.56%, and the kinetics was also investigated. The prepared different composite membranes were characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, thermal gravimetric analysis (TGA) to investigate the surface morphology of fabricated structures, functional groups on the surface of nanofibers and thermal properties. The prepared TEMPO oxidized BSCN based composite membranes can be used as an excellent substrate in the elimination of methylene blue, which is promising in the development of environment-friendly water purifying materials.
