Thermal analysis and electron paramagnetic resonance (EPR) spectroscopy show MC significantly improves SO oxidation stability without compromising dielectric properties. MC-doped SO exhibits > 10 °C higher oxidation onset temperature and delayed thermo-oxidative decomposition due to potent radical scavenging.

Surface and structural analyses revealed that KOH reactivation formed pores through chemical drilling with potassium functioning as an activation agent, while steam reactivation formed pores through widening the interparticle space (etching outer layers of the carbon particles). Therefore, the pore size distributions of activated carbon fibers could be controlled through KOH or steam reactivation.
