Abstract:
The object of the present invention is to realize a separator that has excellent thermal stability in size, shape, and the like even in a high temperature environment. The separator comprises a nonwoven fabric obtained by subjecting a nonwoven fabric consisting of homo-PAN fibers to a flame proofing treatment in a temperature range of 210° C. to 300° C., wherein an I D /I N  value, which is a ratio of an absorption peak intensity I D  of a carbon double bond-derived region (1580-1610 cm −1 ) of the homo-PAN nonwoven fabric to an absorption peak intensity I N  derived from a nitrile group (2240 cm −1 ), as determined by infrared absorption spectroscopy, is 0.07 or more; and wherein a fiber shape and size are stably maintained after immersion for 30 minutes in an electrolytic solution containing propylene carbonate at 140° C.

Claim (Index 1):
A separator for an electric double layer capacitor, wherein the separator comprises a nonwoven fabric obtained by subjecting a nonwoven fabric consisting of homo-polyacrylonitrile (homo-PAN) fibers to a flame proofing treatment in a temperature range of 210\u00b0 C. to 300\u00b0 C., wherein an I D /I N  value, which is a ratio of an absorption peak intensity I D  of a carbon double bond-derived region (1580-1610 cm \u22121 ) of the homo-PAN nonwoven fabric to an absorption peak intensity I N  derived from a nitrile group (2240 cm \u22121 ), as determined by infrared absorption spectroscopy, is 0.07 or more; wherein a fiber shape is maintained after immersion for 30 minutes in an electrolytic solution containing propylene carbonate at 140\u00b0 C.; and both dimensional change rates in longitudinal and lateral directions are 0% or more.
