Synthesis and Characterization of Polyvinyl Chloride Matrix Composites with Modified Scrap Iron for Advanced Electronic, Photonic, and Optical Systems

Abstract

In this study, Fe2O3 powder was synthesized using the co-precipitation method from scrap iron, which was then treated with varying concentrations of copper. Afterwards, the modified Fe2O3 was reinforced in the PVC matrix by using the solution-casting method to synthesize PVC composite films, which were subjected to a UV-visible spectrophotometer, a Fourier transform infrared spectrophotometer, an X-ray diffractometer, and a thermal gravimetric analyzer to evaluate the optical, chemical, structural, and thermal properties. FTIR analysis reveals the formation of the composite through vibrational bands pertaining to both components present, whereas no significant changes in the XRD patterns of PVC were observed after the doping of modified iron oxide, which reveals the compatibility of fillers with the PVC matrix. The optical properties of the copper-doped iron oxide-PVC composites, including absorbance, refractive index, urbach energy, and optical as well as electrical conductivity are measured, and show an increase in optical activity when compared to the pure PVC compound. Moreover, the increased thermal stability of the synthesized composite was also observed and compared with conventional compounds, which, in accordance with all the other mentioned properties, makes the copper-dopped iron oxide-PVC composite an effective material for electronic, photonic, and optical device applications.

The Influence of NBR Waste Modified with SiO2/Not Modified on Processability, Physical-Mechanical and Structural Properties of PVC

“…Thus, PVC bands can be observed at 2872 and 2927 cm -1 (stretch vibration of the -CH bond); The band from 1424 cm -1 (wagging of CH2), 1333 cm -1 (deformation of CH2 bond from CH-Cl group), the band from 1273 and 1073 cm -1 (the stretching vibration of the C-H bonds from the -CH-Cl group) and the one at 963 cm -1 (rocking of CH2). The band at 614.27 cm -1 is associated with the (Hashmi et al, 2022). The bands coming from dibutyl phthalate can be identified at 1724 cm -1 (the stretching vibration of the C=O ester group), at 1600 and 1580 cm -1 (stretching vibration of the aromatic ring structure) and those of 1122 and 1073 cm -1 are attributed to C-O stretching vibration (Kumari and Kaur, 2022).…”

A brief review on preparation and application of MWCNT-based polymer nanocomposites

“…These nanoscaled fillers are embedded in a continuous phase of polymer, metal or ceramics matrix [4]. Almost all varieties of polymers are used as matrices such as thermoplastics; polyurethane (PU) [5], polyethylene (PE) [6], polyvinyl chloride (PVC) [7], thermosets; epoxy polyimide [8] and phenolic resin [9] and elastomers; polybutadiene (PB) [10], ethylene-octene copolymer (EOC) [11]. These fillers may be of 0 dimensional (0D), one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D).…”
