“…1 (c), are present in region B. These inclusions have the characteristic structure of the quinoline-insoluble (QI) particles, as reported by other researchers [2] , [3] , [4] , [5] , [6] , [7] . They exist fairly extensively inside binding carbon, which is derived from coal tar pitch, but rarely inside the petroleum-derived coke.…”

The data in this article are related to the research article “Mesoscopic structure features in synthetic graphite” (März et al., 2018) [1]. Details of the manufacture of isostatically moulded graphite (iso-graphite), thin foil preparation by focused ion beams (FIB) for analysis, and characterisation methods are provided. The detailed structures of coke filler and binding carbon are presented through scanning electron microscopy (SEM), scanning transmission electron microscopy (STEM) and Raman spectroscopy characterisation. Atomistic modelling results of mesoscopic structural features are included.

“…[50][51][52] Moreover, the rst-order D1 and D2 bands, the D + G second-order band and the one located at 2462 cm À1 are also observed, as previously reported for graphite samples. 38,49,53,54 The analysis of the spectra of the thin lms synthesized is not straightforward because these signals cannot be isolated from the background graphite plate signal, which, furthermore, may be slightly different depending on the illuminated zone owing to the random orientation of the graphite particles that comprise the graphite plate. The spectrum of the mesoporous silica thin lm is almost equal to that from the graphite plate because the signal of the silica is much less intense than that of carbon materials.…”

“…The peak appearing at low wavenumbers was the D-band, which was generally located between 1300 and 1400 cm −1 . The G-band is induced by crystalline graphitic/sp 2 carbon atoms and involves out-of-phase intra-layer displacement in the graphene structure; the latter originates from sp 3 hybridization and relates to polycrystalline imperfect graphite [66,69]. The peaks at 201 and 720 cm −1 are the characteristic peaks of MXene [37,51].…”

The limitations of hydrophilicity, strength, antibacterial activity adsorption performance of the biobased and biocompatible polymer materials, such as polyhydroxyalkanoates (PHAs), significantly restrict their wider applications especially in medical areas. In this paper, a novel composite membrane with high antibacterial activity and platelet adsorption performance was prepared based on graphene oxide (GO), MXene and 3-hydroxybutyrate-co-hydroxyvalerate (PHBV), which are medium-chain-length-copolymers of PHA. The GO/MXene nanosheets can uniformly inset on the surface of PHBV fibre and give the PHBV—GO/MXene composite membranes superior hydrophilicity due to the presence of hydroxyl groups and terminal oxygen on the surface of nanosheets, which further provides the functional site for the free radical polymerization of ester bonds between GO/MXene and PHBV. As a result, the tensile strength, platelet adsorption, and blood coagulation time of the PHBV—GO/MXene composite membranes were remarkably increased compared with those of the pure PHBV membranes. The antibacterial rate of the PHBV—GO/MXene composite membranes against gram-positive and gram-negative bacteria can reach 97% due to the antibacterial nature of MXene. The improved strength, hydrophilicity, antibacterial activity and platelet adsorption performance suggest that PHBV—GO/MXene composite membranes might be ideal candidates for multifunctional materials for haemostatic applications.
