More specifically, the present invention relates to metal oxide-nanocellulose fibers, a porous film comprising the same, and a separator for a secondary battery manufactured therefrom, wherein a metal oxide is chemically bonded to a surface of nanocellulose without using an organic binder, thereby providing excellent heat resistance at high temperatures and enabling a relatively thin film.",
