Abstract
The nanofibrous based on the polymer blend that was associated with poly vinyl alcohol (PVA) and poly acrylamide(PAAm) (50/50 wt.%), doped with different ratios of iron oxide nanoparticles (AgNPs) were successfully synthesized using the electrospun method at room temperature(RT) and voltage (12kV). The products were studied using (FESEM), (AFM), (FT-IR), (XRD), and (UV–Vis) technique. The result of FESEM analysis showed that the polymer blend and doped samples produce a random distribution of fine fibers at an average diameter range (219.68, 1111, 1468.42, 400, and 925 ) nm with a smooth surface. FTIR analysis showed may be attributed to physical hydrogen bonding interactions between the functional groups of the polymer mix and the AgNPs. The presence of semi-crystalline aggregates of polyvinyl alcohol (PVA) and polyacrylamide (PAAm) was established using X-ray diffraction (XRD) examination. Additionally, a rise in the additive led to the emergence of a cubic crystalline phase of 7wt.%.Ag. The value allowed indirect E_g^opt decreased with increasing the AgNPs.The Wemple-DiDomenico model was used to derive dispersion parameters such as Eo, Ed, M-1, M-3, and the result of calculating the E_g^opt by this model was compatible with that value calculated by the Tauc relation. Also, there was a inecrease in Urbach energy values with the increase of AgNPs, which caused an increased degree of crystallinity.
