WebCarbon fibers prepared from boron-doped polyacrylonitrile gel fibers were graphitized at 1600~2400℃, and the graphitized fibers were characterized by inductively coupled plasma atomic emission spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction and mechanical tests …
WebMar 8, 2024 · The nanofilaments are in fact the innovatively chopped version of brittle, highly graphitized polyacrylonitrile precursor nanofibers. The high temperature (1250 °C) graphitization and then fast cooling bring about biphasic nanofibers made of graphite and amorphous carbon, readily reoxidized during cooling. WebNov 29, 2024 · Electrohydrodynamic forces are applied via electrospinning to unwind and orient the molecular chains of a non-graphitizing carbon precursor, polyacrylonitrile. Subsequently, exerting mechanical stresses further enhances the molecular alignment of the polymer chains during the formative crosslinking phase.
