First claim
Opening claim text (preview).
The invention claimed is: 1. A flexible carbon fiber nonwoven fabric obtained by carbonizing a nonwoven fabric obtained by electrospinning a composition comprising an electrospinnable polymeric substance, an organic compound, and a transition metal, wherein the flexible carbon fiber nonwoven fabric has a ratio Id/Ig of the peak intensity Id near 1,355 cm −1 to the peak intensity Ig near 1,580 cm −1 , as a measured by Raman spectroscopy, in a range of 0.7 to 1.3, wherein the ele…
