In this work, synthesis and swelling behavior of a superabsorbent hydrogel based on Pectin (Pc) and polyacrylonitrile (PAN) were investigated. A mechanism for hydrogel formation was proposed and the structure of the product was established using FTIR spectroscopy. The Pc-poly (sodium acrylate-co-acrylamide) hydrogel exhibited a pH-responsive swelling-deswelling behavior at pH’s 2 and 8. This on...

Nano materials possess unique mechanical, physical, and chemical properties. They are small, and have an ultrahigh surface area, making them suitable for air filter applications since air filtration is necessary to protect sensitive components from harmful particulates and gaseous contaminants. The electrospinning method has been recognized as an efficient technique for fabricating polymer nano...

Catalytic substrate, which is devoid of expensive noble metals and enzymes for hydrogen peroxide (H₂O₂), reduction reactions can be obtained via nitrogen doping of graphite. Here, we report a facile fabrication method for obtaining such nitrogen doped graphitized carbon using polyacrylonitrile (PAN) mats and its use in H₂O₂ sensing. A high degree of graphitization was obtained with a mechanical...

Novel nanostructured hybrid electrospun polyacrylonitrile (PAN) yarns with different graphene ratios were prepared using liquid crystal graphene oxide (LCGO) and PAN. It was found that the well-dispersed LCGO were oriented along the fiber axis in an electrified thin liquid jet during electrospinning. The graphene oxide sheets were well dispersed in the polar organic solvent, forming nematic liq...

In this study, polyacrylonitrile/cellulose acetate (PAN/CA) composite nanofiber membranes with different boehmite contents are prepared by electrospinning. The physical and electrochemical properties of the membrane as a separator in lithium batteries investigated. contrast to commercial polypropylene (PP), nanocomposite fiber has 3D network structure, higher porosity, thermal stability, electr...

Nanocomposites containing polyacrylonitrile (PAN) different mass contents strontium hexaferrite (SFO) were prepared using the casting method. nanocomposite samples characterized by techniques such as field-emission scanning electron microscopy, Four...

Polyacrylonitrile (PAN) is among the most common polymer materials in world thanks to its versatility a wide range of applications. Of importance this work use electrochemical cells. PAN has seen as separator material and binder lithium-ion Expanding upon innovations made recent decades for electrodepositing onto conductive surfaces, details methods used apply thin coating graphite composite el...

In this study, the mechanical properties of 3D printed polylactic acid (PLA) samples produced with fused deposition modeling (FDM) technology five different infill patterns; trihexagon, triangle, line, gyroid, and grid, these patterns were compared for their properties. second part PLA specimens covered polyacrylonitrile (PAN) nanofibers synthesized by electrospinning method to enhance poor ten...

This paper reviews the experience gained over the past few years in two techniques of liver support, charcoal haemoperfusion and polyacrylonitrile membrane haemodialysis. Problems with charcoal haemoperfusion have centred around platelet aggregation and hypertension, and new carbon preparations with a variety of different coatings to overcome these problems are described. Haemodialysis using th...

To improve the mechanical strength and antipollution properties of membranes, this research presents a facile method to prepare crosslinked polyacrylonitrile (PAN) membranes. This was achieved firstly by radical copolymerization with acrylonitrile, allyl methacrylate and sulfobetaine methacrylamide. Then, the copolymer was crosslinked by a thiol-ene click reaction under UV irradiation. Finally,...
