Preparation and Characterization of the Amidoxime-Modified Polyacrylonitrile (PAN-Amidoxime) Nanofibre Composite

Abstract:

In this research, a kind of nonwoven composite used for the absorption of heavy mental ions has been made. The composite was made of two layers of ES thermal bonded nonwovens as the protective layers and the PAN-amidoxime nanofibers which are prepared through the modification of electrospun PAN nanofibers as the interlayer. The composition was achieved by the ultrasonic bonding method. After the composition the PAN nanofibers were modified by grafting the amidoxime group to PAN. The results of FT-IR spectra and FE-SEM indicated that nitrile groups in PAN were partly converted into amidoxime groups and there were no serious cracks on the surface of PAN-amidoxime nanofibers. The results show that the amidoxime groups have been proved to be grafted to the PAN nanofibers with the percent grafting of 81.6%.
