The study of biopolymers and their derivative materials had received a considerable degree attention from researchers in the preparation novel material. Biopolymers derivatives have wide range applications as result bio-compatibility, bio-degradability non-toxicity. In this paper, chitosan reacted with different aldehydes(2,4 –dichloro- benzaldehyde or 2-methyl benzaldehyde), ketones (4-bromoac...

In this paper, a new method is proposed for the production of MWCNTs/PVC (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. In this method, a spray is used to produce layers of carbon nanotubes within a PVC matrix. Various parameters influence the production of the nanocomposite and its mechanical properties. These parameters are studied separately and the effect of each of par...

The current work deals with the synthesis and characterization of strontium titanate (SrTiO3) nanoparticles reinforced polyvinyl chloride (PVC) polyvinylidene fluoride (PVDF) blend nanocomposite films prepared via a solution casting approach. structural, thermal, morphological characteristics PVC/PVDF/SrTiO3 were explored through Fourier transform infrared spectroscopy- FTIR, X-ray diffraction–...

Abstract An innovative cost-effective and lead-free polymer nanocomposite of polyvinyl alcohol/ pyrrolidone was developed. PVA/PVP film contained spherical AgCl SnO 2 nanoparticles facilely prepared via a one-pot synthesis method. The route affords uniform dispersion the both unique features insoluble, dense, nonporous properties. new achieved an efficient gamma radiation attenuation capability...

Hot-stage/Fourier transform infrared microspectroscopy (FTIR-M) was used to determine the diffusivities of a series of dialkyl phthalates in poly(viny1 butyral) (PVB) spin-coated films. The diffusivities ranged from lo-'' to lo-'' cmz/s for the isotherms investigated (60" to 150°C). In their respective temperature regimes, dimethyl phthalate and diethyl phthalate exhibited nonlinear diffusion b...

There has been a significant and growing concern over nosocomial medical device infections. Previous studies have demonstrated that embedding nanoparticles alone (specifically, zinc oxide [ZnO]) in conventional polymers (eg, polyvinyl chloride [PVC]) can decrease bacteria growth and may have the potential to prevent or disrupt bacterial processes that lead to infection. However, little to no st...

Simultaneous solar photocatalytic decolorization of Methlene Blue (MB) dye and degradation polymer nanocomposite film in water has been attempted the present work. The immobilized iron (Fe)-doped zinc oxide (ZnO) nanoparticles (NPs) polyvinyl chloride (PVC) matrix. This reduced cost separation from treated water. Doped NPs were prepared sonochemically using acetylacetonate (0.95 mmol) ferric (0...
