Synthesis of calixamide nanofibers by electrospinning and toxic anion binding to the fiber structures

摘要: Abstract This study reports the synthesis of three novel polyacrylonitrile (PAN) nanofibers based calixamide containing pyridine groups by electrospinning. The structures newly prepared were clarified using spectroscopic techniques. Analysis indicated that preparation was successfully achieved. presence calixarene molecules in nanofiber backbones confirmed Fourier transform infrared (FTIR-ATR), scanning electron microscope (SEM), and thermogravimetric analyses (TGA DSC). toxic anion binding studies exhibited nanofiber-based could be efficiently used for chromate anions as a model oxoanion. Nanofiber may good candidate filter material water purification waste treatment owing to their very large surface area well inclusion complexation capability all surfaces associated with skeleton.
