Abstract
Electrospinning is a straightforward, inexpensive and quick method for the fabrication
of nanofibres and nanofibre-based materials. In this work, electrospun polyacrylonitrile
(PAN) nanofibres embedded with silver phosphate (Ag3PO4) have been fabricated.
Electrospun PAN nanofibres were surface modified with hydrazine to form amidoxime
groups —C(CN2=NOH) for effective anchoring of silver ions, which is then converted
to silver phosphate through chemical methods. The composite fibres that were produced
in this way were evaluated using a Scanning electron microscope(SEM), Fourier transform
infrared (FTIR), Ultraviolet-visible(UV-vis) and X-ray Powder Diffraction(XRD).
Photocatalytic behaviour and antibacterial testing were done on the composite and analyzed.
According to experimental findings, composite nanofibres made by reacting
functionalized PAN nanofibres with 0.02Mconcentration solutions of silver nitrate and
disodium hydrogen phosphate are found to be more effective in the photo-degradation
of dyes when exposed to visible light and for antibacterial activity, PAN nanofibres
fabricated by utilization of 0.05 M concentration solutions was found to be the most
effective.
