Abstract
Abstract PVA/Chitosan nanocomposite fibers were prepared by electrospinning method. The weight ratio of PVA:Chitosan was fixed at 80:20 in 2% Acetic acid. The concentration of the PVA/Chitosan solution was varied from 3 to 5 wt%. The viscosity of precursor solution was determined by Ubbelohe viscometer. The results revealed that the mixture solution viscosity is directly proportional to its concentration. The morphology and diameter of PVA/Chitosan nanocomposite fibers were characterized by scanning electron microscopy and atomic force microscopy. The diameter of as-prepared PVA/Chitosan nanocomposite fiber was approximately 100 nm. The suitable concentration condition of the solution for fiber formation is 5wt% due to the maximum fiber yield. Fourier Transform Infrared Spectroscopic measurement exhibited the existence of relevant functional groups of both PVA and Chitosan in the composites.

Sixteen -ply quasi -isotropic composite laminates of plain and interleaved AS4/3501 -6 composite laminates clamped all around were impact tested to assess the improvement in impact resistance of composite laminate that has been interleaved by electrospun Nylon 66 nanofabric. The impact velocit y, force, and energy were ranged from 2.0 to 4 m/s, 900 to 2,100 N and 0.46 to 1.8 J, respectively. Based on this preliminary study, results showed that ; polymer nanofabric interleaving marginally increas...

Abstract In this study, the electrospinning of chitosan has been investigated. The problem of chitosan high viscosity, which limits its spinability, is resolved through the application of an alkali treatment which hydrolyzes chitosan chains and so decreases its their molecular weight. Solutions of the treated chitosan in aqueous 70–90% acetic acid produce nanofibers with appropriate quality and processing stability. Decreasing the acetic acid concentration in the solvent increases the mean diame...

Abstract Electrostatic interaction between opposite charge of drugs (insulin and benzoic acid) and chitosan was studied by 1H NMR, FTIR and isothermal titration calorimetry (ITC). No ionic interaction between the carboxyl group of benzoic acid and the amine group of chitosan could be detected. There was a minor change in the FTIR spectra of insulin–chitosan microparticles made of different concentrations of insulin. Exothermic heat of reaction between insulin and chitosan was obtained by ITC. Ho...

A novel micro-extraction procedure was developed through the use of an electrospun polymer nanofiber as a solid-phase extraction (SPE) sorbent to directly extract trazodone from human plasma. The target compound was then monitored by a high performance liquid chromatography with ultraviolet detector (HPLC-UV) system. Parameters of influencing the extraction efficiency, such as fiber diameter, fiber packing amount, eluted solvent, pH and ionic strength were investigated. Under the optimized condi...

A series of poly (vinyl alcohol) (PVA)/chitosan (CS) blend nanofibrous membranes with different weight ratio of PVA to CS were fabricated by electrospinning method. The morphology, diameter, and structure of electrospun nanofibers were investigated by scanning electron microscopy (SEM), fourier transform infrared (FT-IR), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). SEM images showed that the morphology and diameter of the nanofibers were mainly affected by concentration ...

Abstract The purpose of this study was to produce a well-characterised electrospun polystyrene scaffold which could be used routinely for three-dimensional (3D) cell culture experimentation. A linear relationship ( p 0.01 ) between three principal process variables (applied voltage, working distance and polymer concentration) and fibre diameter was reliably established enabling a mathematical model to be developed to standardise the electrospinning process. Surface chemistry and bulk architectur...

Abstract Nanofibers with average diameters between 20 and 100 nm have been prepared by electrospinning of 82.5% deacetylated chitosan ( M v = 1600 kDa) mixed with poly(vinyl alcohol) (PVA, M w = 124–186 kDa) in 2% (v/v) aqueous acetic acid. The formation of bicomponent fibers was feasible with 3% concentration of solution containing up to an equal mass of chitosan. Finer fibers, fewer beaded structures and more efficient fiber formation were observed with increasing PVA contents. Nanoporous fibe...

In this study, a novel hybrid multilayered electrospun nanocomposite membrane (MENM) was developed for activated wound dressing applications. An established electrospinning process was employed to fabricate a tri-layer nanocomposite membrane where the lower layer was composed of chitosan (CS)/polyvinyl alcohol (PVA) and fibrin (having regeneration of tissues and bleeding resistance properties), both of which are directly in contact with the burn wound (BW) skin, and a middle layer of PVA/sodium ...

Purpose Today, the development of wounds and their side effects has become a problematic issue in medical science research. Hydrogel-based dressings are some of the best candidates for this purpose due to their ability to keep the wound bed clean, as well as provide proper moisture, tissue compatibility and an antimicrobial effect for wound healing. On the other hand, copper and its compounds have been used experimentally for many years in studies as an antimicrobial substance. Various studies h...

The filler mass of AgNPs in the Ag/PVA nanofiber composites was varied from 0.025 to 0.125 g. X-ray diffraction (XRD) analysis was used to determine the structure, crystal size, and lattice parameter of powdered AgNPs. Fourier transform infrared (FTIR) spectroscopy was used to determine the functional groups of the samples. Scanning elect...

Electrospun polymer nanofibers (EPNFs) as one-dimensional nanostructures are characterized by a high surface area-to-volume ratio, high porosity, large number of adsorption sites and high adsorption capacity. These properties nominate them to be used as an effective adsorbent for the removal of water pollutants such as heavy metals, dyes and other pollutants. Organic dyes are considered one of the most hazardous water pollutants due to their toxic effects even at very low concentrations. To over...

Inducing the formation of new blood vessels (angiogenesis) is an essential requirement for successful tissue engineering. Approaches have been proposed to enhance angiogenesis using growth factors and other biomolecules; however, this approaches present drawbacks in terms of high cost and patient safety. Copper is known to effectively regulate angiogenesis and can offer a more cost-effective alternative than the direct use of growth factors. With this study, a strategy to incorporate copper in e...
