摘要：

Here we fabricate hi.-h-purity carbon sheets consisting of 250 nm nanofibers through the fibre formation of poly (benzimidazol) by electro-spinning and subsequent heat treatment up to 3000 degreesC without the stabilization process (the most time-consuming step). The non-graphitic character of these nanofibers is due to: (1) the low graphitization-ability of the polymer itself, (2) the limited graphitization of the size effect (small diameter) (3) the existence of internal pores formed during the electrospinning process.
