titleOfInvention | Polyolefin separator and the method of preparing the same |
abstract | The present invention provides a polyolefin separator which can reduce the thickness and weight of a composite separator having a conventional organic / inorganic coating layer and has an equivalent level of heat resistance, comprising the steps of: extruding a resin composition containing a polyolefin and a plasticizer; Stretching the extruded resin composition to obtain a polyolefin film; Extracting the plasticizer from the obtained polyolefin film to obtain a porous polyolefin film; Coating at least one surface of the porous polyolefin film with a composition for forming a porous coating layer comprising an epoxy resin, a curing agent and an organic solvent; And a step of thermally fixing the porous polyolefin film coated with the composition to obtain a composite separator having a porous coating layer formed thereon. |
