SHEET-LIKE FIBER STRUCTURE, AND BATTERY, HEAT INSULATION MATERIAL, WATERPROOF SHEET AND SCAFFOLD FOR CELL CULTURE, EACH USING THE SHEET-LIKE FIBER STRUCTURE

摘要

Disclosed is a sheet-like fiber structure which comprises a plurality of fibers that are formed from amorphous silicon dioxide. The plurality of fibers are intertwined and thus connected with each other, thereby forming void portions. Consequently, the sheet-like fiber structure has not only liquid permeability and voltage resistance but also high heat resistance and chemical resistance. The sheet-like fiber structure is therefore applicable to a separator for preventing a short circuit between electrodes, a scaffold for cell culture and the like.
