“…Among semiconductor nanoparticles, zinc oxide and titania with wide band gaps are widely used as photocatalyst [16,17]. Titania and zinc oxide needs UV irradiation due to their wide band gap excitation [18][19][20]. The wavelength of light that can be absorbed by a semiconductor photo-catalyst is depends on band gap.…”

The main aim of this study is the design and fabrication of degradable nanocomposite films composed of starch/gelatin (S/G)/SiO2 suitable for food packaging applications. Response surface methodology (RSM) was applied to design the fabrication process and to investigate the effect of S/G weight ratio and SiO2 weight percent (wt.%) on the mechanical and barrier properties of the prepared samples. The results revealed that tensile strength and modulus were increased with increasing S/G wt. ratio and introducing SiO2 into the polymer matrix, while elongation at break and water vapor permeability (VWP) decreased. The process optimization was done and various properties of the optimized films such as morphological properties, thermal properties, VWP, degradability, and antibacterial properties were investigated. It was found that the thermal stability of the optimized sample as well as its barrier property against water vapor were improved dramatically as SiO2 presented into the matrix due to proper dispersion and interaction of nanoparticles with the polymer matrix as also confirmed via scanning electron microscopy images. Furthermore, SiO2 has brought significant antibacterial properties for the S/G matrix that is a notable feature for food packaging films. Overall, the results of the current study confirm the S/G/SiO2 compounding could be proper candidate for fabrication of antibacterial degradable food packaging films. POLYM.

In this study, an investigation of the rheological behavior of starch/poly(vinyl alcohol) (PVA)/titanium oxide (TiO 2 ) nanofluids was performed. It revealed that the rheological behavior of starch suspensions displays a particular change due to the presence of PVA and TiO 2 . All examined fluids demonstrated non-Newtonian behavior and followed the Power law model. The main and interacting effects of starch, PVA, and TiO 2 nanoparticles concentrations were studied using the analysis of variance. The results indicated that the flow behavior index (n), as well as the consistency index (K) of suspensions, is influenced by the PVA and TiO 2 contents. The flow behavior index (n) decreased and consistency index (K) increased by an increase in PVA concentration. A reverse trend is observed by the addition of TiO 2 nanoparticles to starch and PVA blend suspensions. The difference in rheological behaviors was ascribed to the presence of binary and triplet interactions between starch, PVA, and TiO 2 nanoparticles. V C 2016 Wiley Periodicals, Inc. J. Appl. Polym.
