The Interaction Effects of Montmorillonite and Glycerol on the Properties of Polyvinyl Alcohol-montmorillonite Films
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...
متن کاملLate presentation of polyvinyl alcohol sponge (Ivalon) aortic graft failure.
A 20-year-old woman was found to have hypertension (160/100 mmHg) during a pregnancy in 1955. A diagnosis of coarctation of the aorta was confirmed and at operation in 1956 the coarctation was found to begin 2-5 cm below the origin of the left subclavian f artery and to extend 5 cm distally. After excision of the stenotic segment continuity was restored with an Ivalon graft, end-to-end anastomo...
متن کاملSynthesis of polynucleotide analogs containing a polyvinyl alcohol backbone.
Water soluble homo-base polynucleotide analogues were synthesized in which polyvinyl alcohol and partially phosphonated polyvinyl alcohol constituted the backbones,onto which were grafted uracil or adenine via 1,3-dioxane spacers formed by acetal formation with the 1,3-diol moieties in PVA. The resulting adenine-PVA polynucleotide analogs exhibited hyperchromic effects, which was not the case f...
متن کاملSynthesis 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....
