synthesis and enhanced mechanical properties of nano zinc oxide in polyvinyl alcohol and polyvinyl pyrollidone composite film

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 (20150 nm) before incorporate in to the polymer matrix.
