The influence of silver (Ag) nanoparticles on the properties poly(vinyl alcohol) (PVA) was investigated. nanocomposite prepared by mixing a colloidal solution consisting with water PVA in appropriate ratios. Composite films different contents inorganic phase were obtained after solvent evaporation. nanocomposites determined using atomic absorption spectroscopy (AA) for silver, and found to be 0.19, 0.33, 0.73 wt %. Transmission electron microscopy (TEM) revealed presence Ag particles average...
Poly(lactic acid) (PLA) and polypropylene (PP) were comparatively investigated as matrices for injection-moulded composites containing small (1–3 wt%) amounts of short sisal fibre. The morphology, thermal dynamic mechanical properties, well degradation characteristics investigated. scanning electron microscopy (SEM) micrographs the show more intimate contact better interaction between fibres PLA, compared to PP. This improved was confirmed by Fourier-transform infrared (FTIR) spectroscopy...
This paper focuses on the crystalline structure of injection moulding grade poly(lactic acid) (PLA) and effect processing.The research is induced by significant differences in crystallinity pure PLA resin, moulded product, thus reprocessing products.2 mm thick sheets were re-crystallized a conventional oven at 60-140°C, for 10-60 minutes to achieve various contents.The properties these investigated dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), wide angle X-ray...
Herein, novel hybrid nanomaterials were developed for wound dressing applications with antimicrobial properties. Electrospinning was used to fabricate a double layer nanocomposite nanofibrous mat consisting of an upper poly(vinyl alcohol) and chitosan loaded silver nanoparticles (AgNPs) lower polyethylene oxide (PEO) or polyvinylpyrrolidone (PVP) nanofibers chlorhexidine (as antiseptic). The top containing AgNPs, whose purpose protect the site against environmental germ invasion, prepared by...
Poly(vinylidene fluoride) (PVDF) is a piezoelectric material with outstanding physical and mechanical properties. The properties depend on the β-phase content of this polymer, while morphology degree crystallinity material. Silver has antibacterial effects, silver nanoparticles (Ag-NPs) have large surface areas rich in electrons. In paper, we produced electrospun PVDF fibrous mats that contained different contents Ag-NPs between 0% 1.0%. β-content was found to increase by about 8% for...
Abstract The preparation and characterization of modified unmodified polypropylene (PP)–wood powder (WP) composites were done under fixed processing conditions. Different techniques used to study the effect both WP size content, as well compatibilizer on properties composites. results point fact that, settles in amorphous part matrix creates new crystalline phases or zones. Scanning electron microscopy micrographs show a relatively even distribution PP matrix, which contributes improvements...
