The electrodeposition of a polymer (polyacrylonitrile, PAN) is used to reduce the risk thermal runaway in lithium-ion batteries, which most important cause battery accidents and fires. PAN was electrodeposited on graphite electrode, using cyclic voltammetry or chronoamperometry, solution with acrylonitrile as solvent. film characterised by Raman spectroscopy, microscopy, energy dispersive X-ray...

Carbon nanofibers are produced from dielectric polymer precursors such as polyacrylonitrile (PAN). Carbonized nanofiber nonwovens show high surface area and good electrical conductivity, rendering these fiber materials interesting for application electrodes in batteries, fuel cells, supercapacitors. However, thermal processing is slow costly, which why new techniques have been explored carbon t...

BACKGROUND The objective of this investigation was to develop a new class of antibacterial material in the form of nanofibers coated with silver nanoparticles (AgNPs) using a modified coaxial electrospinning approach. Through manipulation of the distribution on the surface of nanofibers, the antibacterial effect of Ag can be improved substantially. METHODS Using polyacrylonitrile (PAN) as the...

We studied the suitability of in vitro dialysis with polyacrylonitrile (PAN) membranes to remove small amounts of interleukin-1(3 (ILlp) and tumor necrosis factor (TNF) from plasma to be used as diluent for the standards in radioimmunoassays (RIA). Incubation o f PAN membrane fragments with radiolabeled IL-1(3 or TNF yielded a significant binding of both cytokines to the membrane (percentage of...

A core/sheath nanofiber membrane with poly[bis(p-methylphenoxy)]phospha-zene (PMPPh) as the sheath and easily spinnable polyacrylonitrile (PAN) as the core was prepared via a coaxial electrospinning process. Field-emission scanning electron microscopy and transmission electron microscopy were used to characterize the morphology of the nanofiber membrane. It was found that the concentration of t...

Electrospun fibrous membranes find place in diverse applications like sensors, filters, fuel cell membranes, scaffolds for tissue engineering, organic electronics etc. The objectives of present work are to electrospun polyacrylonitrile (PAN) nanofibers and PAN-CNT nanocomposite nanofibers and convert into carbon nanofiber and carbon-CNT composite nanofiber. The work was divided into two parts, ...
