“…Notably, the crystallinity of polyethene materials is very low, its reflection peaks therefore did not appear obviously. These results were consistent to Sadek et al[20] and Hasan et al[21] on incorporating ZnO and TiO2 nanostructures PVC matrix. Meanwhile the average crystallite size of the ZnO/TiO2 supported bimetallic composite samples calculated using the Debye-Scherrer's Equation (1) is ~15 nm.…”

This study presents on ZnO/TiO2 supported on PVC (ZnO/TiO2@PVC) in the photocatalytic removal of paraquat dichloride. The ZnO/TiO2@PVC was characterized using XRD, FESEM-EDX, FTIR, and AFM. Findings indicated that ZnO/TiO2@PVC allowed degradation of paraquat dichloride under UV irradiation by the rate of up to 73%. XRD pattern indicated the presence of both TiO2(anatase) and ZnO (zincite) crystalline as well as PVC amorphous structures. FESEM and AFM results revealed the observed shape and surface of TiO2 interconnected nanowires with ZnO nanorods uniformly distributed according to EDX mapping. The reduced surface roughness was also shown in the supported photocatalyst. FTIR analysis clearly demonstrate the combined spectra of immobilised ZnO/TiO2 powder catalyst onto the PVC in the composite. Kinetic study of the degradation process was performed according to pseudo-first-order and the influence of ZnO/TiO2 coating onto PVC polymer and initial paraquat concentration were investigated on the treatment performance. Under optimized condition (pH = 7, PQ =20 mg/L and catalyst coating =15%), the stability and reusability of the supported catalyst was also evaluated over ten sequential treatment runs, and the catalyst maintain high reactivity. High recyclability of the ZnO/TiO2@PVC composites as catalyst in photodegradation processes are also reported in this study.

“…The crystal structure of the Fe 2 O 3 :ZnO material was analyzed by TEM, and the results are depicted in Figure 8 . The hexagonal shape of ZnO [ 28 ], with average particle sizes of 15–30 nm in diameter, was confirmed ( Figure 8 a,b). The lattice fringes of the Fe 2 O 3 and ZnO materials are clearly visible in the high-resolution TEM (EFTEM Jeol 2200 FS, JEOL Ltd., Tokyo, Japan) image of the Fe 2 O 3 :ZnO material ( Figure 8 c), with the interplanar spacing of 0.5 nm and 0.25 nm, respectively [ 29 ].…”

In this report, a Fe2O3:ZnO sputtering target and a nanograins-based sensor were developed for the room temperature (RT) detection of hydrogen peroxide vapor (HPV) using the solid-state reaction method and the radio frequency (RF) magnetron sputtering technique, respectively. The characterization of the synthesized sputtering target and the obtained nanostructured film was carried out by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray (EDX) analyses. The SEM and TEM images of the film revealed its homogeneous granular structure, with a grain size of 10–30 nm and an interplanar spacing of Fe2O3 and ZnO, respectively. EDX spectroscopy presented the real concentrations of Zn in the target material and in the film (21.2 wt.% and 19.4 wt.%, respectively), with a uniform distribution of O, Al, Zn, and Fe elements in the e-mapped images of the Fe2O3:ZnO film. The gas sensing behavior was investigated in the temperature range of 25–250 °C with regards to the 1.5–56 ppm HPV concentrations, with and without ultraviolet (UV) irradiation. The presence of UV light on the Fe2O3:ZnO surface at RT reduced a low detection limit from 3 ppm to 1.5 ppm, which corresponded to a response value of 12, with the sensor’s response and recovery times of 91 s and 482 s, respectively. The obtained promising results are attributed to the improved characteristics of the Fe2O3:ZnO composite material, which will enable its use in multifunctional sensor systems and medical diagnostic devices.

“…ZnO, TiO 2 , and Fe 2 O 3 NPs can be seen in a reasonably uniform distribution in the PVC matrix at 10 wt%. 87 However, their agglomerated structures were seen when utilized at 15 wt%, as depicted in (Figs. 15d-15f) left one.…”

“…For instance, ZnO altered the thermo-mechanical characteristics of neat PVC TiO 2 NPs dispersion in PVC and improved dynamic mechanical response (i.e., storage modulus and loss factor tan) of composites ZnO, Fe 2 O 3 . 81 Preparation method.-According to Sadek et al, 82 by applying the same process TiO 2 from TiCl 4 , Fe 2 O 3 , and ZnO nanoparticles from their hydrated nitrate salts, Zn(NO 3 ) 2 H 2 O and Fe(NO) 3 H 2 O were obtained respectively.

“…Additionally, the TEM images showed hexagonal TiO 2 with a size of 12-30 nm. 82 The mechanical strength of the nanocomposites is also characterized in terms of their storage modulus, loss modulus, and loss factor. The well-dispersed behavior of ZnO, TiO 2 , and Fe 2 O 3 NPs at 10 wt% in the PVC matrix helped to demonstrate the higher values of storage modulus E′ and loss modulus E′′ of composites compared with the PVC matrix.…”

PVC (polyvinyl chloride) is a thermoplastic polymer used extensively in industrial applications. The potentiality of PVC lies in various parameters, such as high tensile strength, biodegradability, large surface area, chemical stability, low weight, durability, cost-effectiveness, and availability. However, the low thermal stability and brittleness of pure PVC limit its acceptance in widespread applications. Therefore, modifying PVC with metal oxides and carbon nanofillers could substantially improve thermal stability, mechanical strength, biocompatibility, surface area, conductivity, etc. Enhanced properties in modified PVC result from the chemical and physical interaction between polymer and functionalized nanofillers and the good dispersion capability of nanofillers on polymer matrix, which is attributed to the excellent performances of nanocomposites in diverse fields. This paper aims to present an overview of the characterization, preparation, and applications of blend nanocomposites of PVC, which would benefit future developments in this field.
