Nano structure of low crystallinity carbon materials analyzed by using high energy X-ray diffraction

Abstract: Abstract:In this study, we tried to characterize a kind of low crystallinity carbon materials. The structure of polyparaphenylene(PPP)-based carbon was analyzed by means of high energy X-ray diffraction using the apparatus of SPring-8. The experimental results revealed the existence of basic structural units (BSU) in the highly disordered materials like PPP-based carbon. It is thought that the PPP-based carbons consist of small turbostratic particles, which have a few piled up poly-aromatic layers. The structu… Show more

“…the atomic coordination spheres they reflect, start losing their sharpness leading to a reduction of the length of structural coherence, measured by the real space distance at which the PDF data decay to zero, to only 20-30Å. Indeed the atomic PDFs for graphitic carbon milled for 70-1270 min resemble very much those of low crystallinity carbon obtained by a thermal decomposition of organic precursors [17,18]. The graphitic planes in those low crystallinity carbon are found to be rich in structural defects and heavily buckled [17].…”
