Abstract: A biaxially oriented polyester film according to the present invention is a biaxially oriented polyester film comprising inorganic particles and a polyester resin, wherein the hardness of a roll obtained by slitting a master roll on which the biaxially oriented polyester film is wound and then by being rewound thereon at a winding tension of 6.5 kg/m to 8.5 kg/m, a winding surface pressure of 35 kg/m to 50 kg/m and a winding rate of 300 m/min to 350 m/min, is 90 to 95 points. The biaxially oriented polyester film prevents the roll from forming wrinkles over time in a roll wound state, and therefore when used as an interlayer of a secondary battery separator, can prevent wrinkles from transferring onto the separator.

Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.
