Beschreibung
Zusammenfassung:	The present invention relates to a separator comprising: a porous support including a matrix including polyolefin having a weight average molecular weight (Mw) of 250,000 to 450,000, and a crosslinked silane-modified polyolefin in the matrix; and an inorganic coating layer positioned on at least one surface of the porous support, and to a manufacturing method thereof. The separator has excellent heat resistance and mechanical properties. 본 발명의 일 측면은, 중량평균분자량(Mw)이 250,000~450,000인 폴리올레핀을 포함하는 매트릭스 및 상기 매트릭스 중에서 가교된 실란 변성 폴리올레핀을 포함하는 다공성 지지체; 및 상기 다공성 지지체의 적어도 일면에 위치하는 무기 코팅층;을 포함하는 분리막 및 그 제조방법을 제공한다.
