چکیده

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 dispersion of nano particles in the polymer matrices is a general prerequisite for achieving desired mechanical and physical properties. particular attention is paid on the structural and mechanical properties of a composite film by sem and measurement of tensile properties.  the results also shows that, the zno nps were uniformly dispersed in the polymer matrix and the particles remained their original size (20-150 nm) before incorporate in to the polymer matrix.

Novel Kefiran-Polyvinyl Alcohol Composite Film: Physical, Mechanical and Rheological Properties

Background and Objectives: Kefiran (Kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. Therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. The expansion of mixed systems can propose kefiran and polyvinyl alcohol (PVOH) as a new composite film. Materials and Methods: Solutions of 20 gr...
