Abstract:

In order to construct membrane materials with special surface/interface properties, amidoxime-modified SiO2/polyacrylonitrile(PAN)nonwovens with highly hydrophilic and underwater super-hydrophobic surface were fabricated using electrospinning and amidoximation with hydroxylamine hydrochloride. The composite nonwovens were characterized by the field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier transform infrared spectrometer and contact angle tester. The results show that the surfaces of the amidoxime-modified nanofibrous nonwovens are covered with floccule, the average diameters of amidoxime-modified SiO2/PAN nonwovens are 275 nm at the optimal volume concentration of 35-40 g/L and the best modification temperature is 60 ℃. The fraction content of Si and O elements on the surface of the modified nanofibrous nonwovens are 2.13% and 6.60%, receptively. All these results demonstrate that SiO2 particles are successfully deposited onto the PAN nonwovens. Comparing with PAN nonwovens (wetting time 5.4 s), after 60 ℃ amidoximation, the wetting time of SiO2/PAN nonwovens is shortened to 0.5 s. Moreover, the underwater oil contact angle of as-prepared composited nonwovens reach (165.2±1)°. The breaking strength of amidoxime-modified nanofibrous nonwovens is 4.1 MPa,and it meet the basic requirements of oil-water separation.
