Sulfur containing atomic group introduced porous article, process for introducing a sulfur containing atomic group onto the outer-inner surfaces of a porous article, and a battery separator

A porous article wherein a sulfur containing atomic group is introduced onto at least a part of outer-inner surfaces of the article,a ratio (S/C) of the number of sulfur atoms (S) to the number of carbon atoms (C) on the surface onto which the sulfur containing atomic group is introduced is 7x10-4 o...

Beschreibung
Zusammenfassung:	A porous article wherein a sulfur containing atomic group is introduced onto at least a part of outer-inner surfaces of the article,a ratio (S/C) of the number of sulfur atoms (S) to the number of carbon atoms (C) on the surface onto which the sulfur containing atomic group is introduced is 7x10-4 or more, a ratio (O/C) of the number of oxygen atoms (O) to the number of carbon atoms (C) on the surface onto which the sulfur containing atomic group is introduced is 0.2 or more, and the ratio (S/C) and the ratio (O/C) are determined by means of an X-ray photoelectron spectrophotometer is disclosed.
