Abstract
A method for improving physical properties of a separator in which is capable of increasing insulation, tensile strength and elongation. The separator also has improved physical properties through the above method. Particularly, the present invention is applied to a separator that has already manufactured. After forming a double bond in the separator that has already manufactured, crosslinking may be formed through the double bond or by adding a separate crosslinking initiator.
