Characterization of Green Syntesized Silver Nanoparticles Doped in Polyacrylonitrile Nanofibers

This paper reports a cost effective and eco-friendly green technique used for the synthesis of silver metal nanoparticle from orange peel extracts. The synthesized nanoparticle was functionalized with polyacrylonitrile to form PAN/Ag nanofibers by electrospinning. The synthesized nanoparticle and its nanofibers were characterized by using spectroscopic and morphology techniques such as fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible (UV-vis) spectroscopy, x-ray diffraction (XRD) spectroscopy, scanning electron microscopy (SEM), EDX to determine the elemental composition of the nanofibers and transmission electron microscope (TEM). The optical studies for the silver nanoparticles were carried out at different concentrations, volumes, and incubation time. The nanofiber diameters were evaluated to be 11, 9, 8, 6 nm for PAN , 6 mg Ag + PAN, 8 mg Ag+ PAN, and 10 mg Ag + PAN nanofibers. SEM of silver nanoparticles showed uniformity in morphology of which is spherical shape, with diameter of 20 nm. Thermal stability of the nanofibers was also investigated using thermal gravimetric analysis
