Porous nanofiber web and method for manufacturing the same

PURPOSE: A porous nanofiber web and a method for fabricating the same are provided to continuously maintain ion conductivity by strongly adhering an ion conductor. CONSTITUTION: A porous nanofiber web contains a porous support and apatite inorganic particles. The porous support is formed of hydrocarbon fiber. The inorganic particles are contains in 1-80 wt% in the porous support. The porous nanofiber web is formed of fiber aggregate(10). The inorganic particles contains at least one among fluoroapatite(Ca_5(PO_4)_3F), chloroapatite(Ca_5(PO_4)_3Cl), and hydroxyl apatite(Ca_5(PO_4)_3(OH)).
