Carbon nanofibers (CNFs) have garnered great attention as promising materials for electric energy storage due to their unique properties and advantages, such as high surface area, high electrical conductivity, chemical stability, low thermal expansion, etc. In this study, a series of organically soluble poly(azomethine ether)s (PAMEs) were synthesized via polycondensation of 3,4’-oxydianiline or 4,4’-oxydianile with 2,5-diformylfuran or 2,5-diformylthiophene. PAME-derived CNFs were fabricated via electrospinning and following heat treatment for carbonization. The morphology and microstructure of PAME-derived CNFs were characterized using SEM, EDS, and XPS. The material has good thermal stability and showed high residual weight at high temperatures, suggesting its potential as a precursor for carbon materials. The electrical and electrochemical properties of the CNFs were probed by CV test, GCD test, and EIS to use electrode materials of supercapacitor.
