Abstract
The present disclosure relates to a separator and a method of manufacturing the separator. The separator includes a porous support and a hydrophilic polymer applied to the surface of the porous support through a solution including the hydrophilic polymer and a solvent, and satisfies the following Equation: 0.015≤(C*D)/(A*B)≤0.65, where A is a thickness (μm) of the porous support, B is an air permeability (Gurley, seconds/100 ml) of the porous support, C is a porosity (% by volume) of the porous support, and D is a content (% by weight) of the hydrophilic polymer in the solution.
