Zinc oxide nanoparticles have been synthesized by chemical reaction method.  Polyvinyl alcohol (PVA) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by PVA solution and nanozinc oxide. Polymer blend with ZnO nanoparticle composite film has prepared by casting technique.  The property of nano composites depends greatly on the chemistry of polymer matrices....

The microstructure and thermomechanical behaviour of a novel fully biodegradable polyvinyl alcohol (PVOH)-based single-polymer composite (SPC) is presented. Three kinds of PVOH stapled fibres, having different melting temperatures and tensile mechanical properties, were considered as a reinforcement, whilst plasticized PVOH granules were selected as a continuous matrix. Calorimetric tests on th...

The aim of this work has been to explore the potential blending polyvinyl alcohol (PVOH) with casein hydrolysates (HCas) obtain self-standing films capable act as carriers lactic acid bacteria (LAB) biocontrol agents against food pathogens. For purpose, PVOH was blended HCas at different weight ratios and blends were incorporated Lactococcus lactis Lactobacillus sakei. Blending resulted in modi...

The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...

Transparent wood (TW), a new type of composite material with good optical transmittance and excellent mechanical properties, has attracted great interest in recent years. In this study, hydrogen peroxide strategy was used on rubber (Hevea brasiliensis Muell. Arg) to eliminate lignin hemicellulose. Subsequently, delignified combined each three impregnants refractive index similar that cellulose ...

Lignin (SCEL) was separated from steam-exploded eucalyptus wood fibers using a supercritical carbon dioxide (scCO2)–ethanol/water composite medium, which compared with traditional industrial alkaline extraction of lignin (AL) and high-temperature ethanol (EL). All three kinds were spray-dried to form microparticles. The obtained SCEL, AL, EL particles mixed poly(vinyl alcohol) (PVOH) prepare fi...

background and objectives: preparation and evaluation of nanocomposite films have become prevalent in recent years. depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. the effects of montmorillonite (mmt), glycerol (gl), and thei...

This study investigates methods for improving the heat resistance of polyvinyl alcohol/alkali lignin foam material (PLFM). Tetraethoxysilane (TEOS) was used as a precursor to prepare PLCFM by a sol-gel method. The PLCFM, prepared with different levels of TEOS, was characterized by Fourier Transform Infrared spectrometry (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric Anal...

The rheological response of blends obtained from quaternized polysulfone and polyvinyl alcohol in N-methyl-2pyrrolidone as against structural peculiarity of polymers from the blend, composition of polymer mixtures, as well as the types of interactions were investigated. Results show that the variation of polyvinyl alcohol composition in the studied system determines changes of the rheological p...
