“…Because of the interaction between polymers and nanofillers, the chain transfer reactions were suppressed; consequently, the degradation process was slowed, and decomposition took place at a higher temperature. 34 Higher levels of a-ZrP loading (!2%) resulted in aggregations of a-ZrP particles and deterioration in film thermal properties. Results from MU and mechanical properties experiments confirmed this trend.…”

Two series of composites, i.e., polyvinyl alcohol (PVA)/oxidized starch (OST)/exfoliated a-zirconium phosphate (POST-ZrPn) and PVA/starch (ST)/exfoliated a-zirconium phosphate (PST-ZrPn), were fabricated using a casting and solvent evaporation method. The composites were characterized by Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), wide-angle X-ray diffraction (XRD), scanning electron microscopy (SEM), tensile testing, and moisture uptake. Compared with PSTZrPn, POST-ZrPn films with the same component ratio showed higher tensile strength (r b ), lower elongation at break (e b ) and improved water resistance. Additionally, in the POST-ZrPn series, r b and e b increased with an increase in a-zirconium phosphate (a-ZrP) loading; however, higher a-ZrP loads resulted in the aggregation of a-ZrP particles. Compared with POST-ZrP0, the values for r b , e b , and water resistance of POST-ZrP3, containing 1.5 wt % a-ZrP, were increased by 128.8%, 51.4%, and 30.2%, respectively.

“…PVA is highly biocompatible, non-toxic and water-soluble polymer that readily reacts with different cross-linking agents to form a gel [38,39]. In addition, semi-crystalline PVA is greatly used as a polymeric matrix for preparation of nanocomposites by economically and environmentally friendly methods due to its easy processability and optical transparency [40][41][42][43].…”

Poly(vinyl alcohol) (PVA)/CdS and PVA/TiO 2 nanocomposite thin films were prepared at different semiconductor nanoparticles ratio (20, 30, 40 and 50 CC) by employing electrospinning method. For the former, CdS nanoparticles were first synthesized using cadmium nitrate (Cd (NO 3 ) 2 ) and sodium sulfide (Na 2 S) in a simple and economical way whereas for the latter, TiO 2 was purchased. Morphology and structure of nanocomposites were characterized by X-ray diffraction (XRD) and scanning electron microscope. The results indicated the cubic and anatase structure of CdS and TiO 2 nanoparticles in PVA matrix, respectively, and proved that nanoparticles were successfully coated by PVA molecules. Optical properties of samples were also characterized by diffuse reflectance spectroscopy. Particle sizes of CdS and TiO 2 , \9 and 15 nm, respectively, were calculated with the results obtained from XRD observation and it was found to be in agreement with the absorption spectra of both nanocomposites. The prepared films at 50:50 ratio, in both PVA/CdS and PVA/TiO 2 , were found to be suitable for application in solar cell as a window layer due to the crystalline phase, favorable band gap (2.53, 3.31 eV) and higher optical transmittance.
