## Abstract Poly(acrylonitrile) (PAN) solutions in __N__,__N__βdimethylformamide were electrospun into webs consisting of 350 nm ultraβfine fibers. The webs were oxidatively stabilized and followed by heat treatment in the range of 700β1000Β°C. Characterization of the microstructure of PANβbased car
