“…This is an indicator that polymeric thick matrix that have been doped with a high ratio of TSF NCs' have a high competence in avoiding the absorption of radiation in the visible spectrum range. An important step forward in the production of a new generation of optical instruments was taken when it was discovered that the reflectance of TSF NCs' could be adjusted and tuned by impressive proper procedure conditions and doping levels on the NPs.The optical band gap energy (E g ) is calculated using Kubelka–Munk function 38 : where R is the reflectance and F(R) is the reflectance coefficient. Figure 8 b shows the relation between (F(R)hʋ) 2 against photon energy (hʋ).…”

Facile assembly, co-precipitation, and drop casting procedures have been used to construct SnO2/SrSnO3/Fe3O4/PVDF flexible nanocomposites. SnO2/SrSnO3/Fe3O4 nanocomposites (TSF NCs') have been successfully incorporated into polyvinylidene fluoride polymers (PF), according to the microstructural exploration of the systems, which was revealed by XRD, EDX, and ATR-FTIR analysis. The FESEM and cross-section areas demonstrated that the addition of TSF NCs' to PF porous material enhanced its surface characteristics and decreased its surface roughness. The optical gap was lowered from 3.90 to 3.07 eV, and it was discovered that both the refractive index and optical conductivity had improved when TSF NCs' were incorporated into PF. According to the observations, the supplement ratios have a profound influence on the dielectric properties of the nanocomposites. Moreover, the electrical parameters of TSF/PF nanocomposite are significantly modified. The TSF/PF magnetic nanocomposite has good magnetic reactivity and can be easily extracted from the aqueous solution using an external magnetic field, as demonstrated by VSM. This research has been conducted to obtain TSF/PF nanocomposites to be used in promising magno-optoelectronic applications.

In this study, it is aimed to produce a non‐carcinogenic and environmentally friendly biodegradable multi‐functional PVA‐based nanocomposite by improving its electrical properties and mechanical strength. For this purpose, BaO nanoparticles produced by the co‐precipitation method, have been added to the PVA matrix between 0.5% and 5% by mass, and thick film nanocomposites have been produced. The structural properties of the samples and the doping particle have been investigated by FTIR, SEM, and XRD. While electrical measurements have been carried out by an impedance analyzer at room temperature between 20 Hz and 15 MHz frequency, tensile tests have been performed by a mechanical tensile device. The addition of 5% BaO nanoparticles not only increased the energy storage capability of PVA significantly (117%) but also managed to reduce the loss factor considerably (77%). Moreover, compared to other samples, PVA/5% BaO nanocomposite also stands out with its higher ac conductivity within the mid‐and high‐frequency range. Furthermore, the 5% BaO nanoparticle additive provided a serious benefit to the mechanical strength of PVA by improving its Young's modulus, toughness, and stress at the break at different rates. As a result, the BaO nanoparticle additive makes PVA a more functional material as well as more technologically desired.

“…12,13 Nevertheless, the practical application of PVA is restricted by its inadequate mechanical properties, insufficient water absorption, and slow water absorption rate, which limit the practical application of PVA. 14,15 Introducing nanofillers into the PVA matrix was considered as an effective method to enhance the mechanical performance, [16][17][18][19] such as graphene oxide, [20][21][22] CuO nanofillers, 23 sodium alginate nanofibers, 24 and porous boron nitride nanofibers. 25 Among these, it has been reported that the mechanical properties and water absorption of PVA matrix can be effectively improved by adding halloysite nanotubes (HNTs) simultaneously.…”

In the biomedical field, polyvinyl alcohol (PVA) sponge has been widely used. In particular, it is considered a potential implant material for repairing soft tissues. However, its insufficient water absorption and mechanical properties limit its application. In this work, a novel PVA/halloysite nanotubes (HNTs)/gelatin ternary composite sponge was prepared by water solution mixing and casting techniques. HNTs and gelatin/PVA solution were mixed at different weight ratios. The structure of the ternary composite sponges was characterized by using scanning electron microscopy. The physical properties of the ternary composite sponges were characterized. The maximum water absorption reached 1783.5% with a rapid water absorption speed at a weight ratio of HNTs/gelatin of 1:8. Owing to its interconnected macroporous structure and good interfacial interaction, its highest compression strength and tensile strength reached 8.22, 1.51 MPa, respectively. In addition, its thermal stability was enhanced as well, which demonstrated that the prepared composite sponge had better performance than the pure PVA sponge by constructing a ternary system. Therefore, the results suggest that the PVA/HNTs/gelatin ternary composite sponge shows a wider application value as a potential material for repairing soft tissue.Highlights A composite PVA sponge with promising applications in tissue engineering. Simple preparation method, water solution mixing and casting techniques. Pioneering a PVA/HNTs/gelatin ternary system sponge. Improved water absorption ability and mechanical properties.
