Studying the Physical Properties of Non-Woven Polyacrylonitrile Nanofibers after Adding γ-Fe2O3 Nanoparticles .

Abstract

This research focuses on preparing and studying the behavior of non-woven polyacrylonitrile (PAN) nanofibers after adding γ-Fe2O3 nanoparticles to (PAN / N, N dimethylformamide (DMF)) solution with (1.45, 4.3, and 7.14) wt. %. In order to achieve the morphology properties, textural directionality, the bonding between iron oxide particles and the PAN matrix, thermal, crystalline, and magnetic properties we did the Field-Emission Scanning Electron Microscopy (FE-SEM), Fourier Transform Near-Infrared Spectroscopy (FT-NIR), Differential Calorimeter Scanning (DSC), X-Ray Diffraction (XRD), and Vibration Sample Magnetometer (VSM). Laboratory analyses demonstrated the significant influence of iron oxide nanoparticles on the characteristics and performance of the composite nanofibers in terms of reduced nanofiber diameter from 109.38±29.70 to 78.17±36.898 nm, the disappearance of beads. In addition to an increase in the crystallinity from 82.43 to 94.28 % accompanied by a larger crystalline size as a result of the polymeric fibers acquiring high magnetic properties after strengthening them with iron oxide nanoparticles, the saturation magnetization (Ms) increases with the increase of iron oxide loading in the nanofibers from (1.426 emu/g) at 1.45 wt.% γ-Fe2O3 to (6.85 emu/g) to 7.14 wt.% γ-Fe2O3 .

Evaluation of the physical properties and filtration efficiency of PVDF/PAN nanofiber membranes by using dry milk protein

“…The FTIR spectrum of the PAN nanofibers showed peaks at approximately 2925 cm −1 , 2244 cm −1 , 1735 and 1,666 cm −1 , which were assigned to the stretching vibrations of CH2, -C≡N, -C=O, and -C=N groups, respectively. The peaks at approximately 1460 and 1270 cm −1 represent the different vibrations of CH and C-O, and the peak at approximately 3618 cm −1 represents the C-H stretching band [33][34][35]. Additionally, the FTIR spectrum of pure PVDF nanofibers presented peaks at approximately 487 and 531 cm −1 , representing the α-phase, and the peaks at approximately 838, 1184, and 1274 cm −1 correspond to the β-phase and the α-phase and β-phase indicate that the PVDF nanofibers are semi-crystalline [36].…”

Removal of Nickel (II) Ions, Low Level Pollutants, and Total Bacterial Colony Count from Wastewater by Composite Nanofibers Film.

“…PAN powder, N, N-dimethylformamide (DMF) solvent, and iron oxide nano-powder ( -Fe 2 O 3 ) were borrowed from the referenced study [30]. GX3007 nickel(II) nitrate hexahydrate with formula (Ni(NO 3 ) 2 .6H 2 O) was supplied from Glentham Life Sciences Limited.…”

“…The reaction between the PAN and -Fe 2 O 3 nanoparticles is shown in Figure 1 [31]. The electrospinning condition for the production of composite nano bers was presented in [30].…”

Al3+-modified ZnO thin film sensor fabricated by the sputtering method: Characterization and a carbon monoxide gas detection study

“…6 However, pure aluminum can be used to enhance the sensitivity and conductivity of zinc oxide nanoparticles, 7 in addition to using its derivatives, such as alumina, to strengthen the thin film obtained from polyacrylonitrile nanofibers 8 and to use it as a grounded metal collector to produce thin films from nanofibers by the electrospinning method. 9,10 Thin-film technology has developed rapidly due to being distinguished by basic characteristics of technological concern, such as cheap cost, accuracy, obsolescence, and shrinkage in the body. [11][12][13][14][15] Thus, thin films have found their way into many modern technological applications, such as the manufacture of electronic circuits, where they are used to construct inductors, resistors, capacitors, crystal diodes, and transistors.…”
