Effects of iron catalyst on the formation of crystalline domain during carbonization of electrospun acrylic nanofiber

Electrospinning of polyacrylonitrile (PAN) solution: Effect of conductive additive and filler on the process

“…Polyacrylonitrile (PAN), whose behaviour in electrospinning is well known [30,[38][39][40][41], was used in the experiments. Electrospun PAN fibres have many possible applications, one of which is the production of carbon nanofibres (CNF) by carbonization of electrospun precursor fibres [17,21,25,26,29,[40][41][42][43][44][45]. CNTs can be used in precursor fibres since CNT filler may effectively resist heat shrinkage in composite fibres during the carbonization process [29].…”

Effect of the graphitization degree for electrospun carbon nanofibers on their electrochemical activity towards VO2+/VO2+ redox couple

“…4d, is rough and lots of iron compound particles are embedded in the fibers. The iron compound may come from the decomposition of AAI during the carbonization process [21].…”

“…With the consideration of the well catalytic graphitization of iron (III) acetylacetonate (AAI) [21][22], the graphitization degree of ECNFs was regulated by changing the sandwiching plates, AAI mass ratio and catalytic graphitization temperature, and the effect of the conversion of carbon structure on their electrochemical activity toward vanadium redox couple was investigated.…”

Preparation and characterization of electrospun LiFePO4/carbon complex improving rate performance at high C-rate

“…Even though LFP/C600 contains a larger percentage of carbon than LFP/C800, crystallinity of carbon in LFP/C800 would be higher than that of carbon in LFP/ C600 because crystallinity and conductivity of carbon increases with increasing heat-treatment temperature [36]. Therefore, it is expected that conductivity of LFP/ C800 has higher than that of LFP/C600.…”
