2026-05-14 NCM-2025-0466 date（Data of the structure, composition, melting and rheological properties of spinnable pitch） doi:10.57760/sciencedb.j00125.00147 en Spinnable pitch was separated using Soxhlet extraction and column chromatography, and its composition, structure, melting behavior, rheological properties, spinning performance, and the properties of pitch-based carbon fibers were characterized. These data consist of relevant figures and tables obtained through testing using instruments such as three-dimensional excitation-emission matrix fluorescence spectroscopy (F-7000 FL), MALDI-TOF (Bruker Ultraflex),FT-IR(NICOLET-FT-IR 380), elemental analyzer (Avario EL CUBE), ¹³C-NMRXPS (Bruker Avance III 600 MHz), (Kratos AXIS ULTRA DLD with an Al Kα X-ray source),GPC (Agilent 1260 instrument,Germany), EPR (Bruker EMXPLUS 10/12) , TG-DTA (8120, Rigaku, Japan) ,RT600 hot stage with an MM25 microscope,DSR (HAAKE MARS 40), Raman spectroscopy (WITec ALPHA 300RAS), XRD (Bruker, Germany, Cu-Kα source radiation),nonofilament tensile tester (ASTM standard D3822-14) and SEM(JSM-7001F) .
