개량된 투수성과 감소된 전기 저항성을 가진 미소다공성 필름
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. (가) 처리되기 이전의 선구필름의 가졌던 부피밀도에 비해 훨씬 작은 부피 밀도를 가지며 평균 기공 크기가 약 200-10,000Å이고 표면적이 최소한 약 10㎡/g인 소수성의 폴리올레핀계로 된 연속기포의 미소 다공성 필름의 미소기공의 표면을 최소한 한개의 2중결합과 최소한 한개의 극성 관능기를 가지며 탄소수 약 2-18 정도의 친수성의 유기탄화수소 단량체 최소한 한가지로 도포하고
    (나) 약 0.1-10wt% 정도의 부착량이 될 수 있으며 미소기공의 연속기포특성을 유지할 수 있을 정도로 미소포상태의 미소다공성 필름 중량에 대해 충분한 량의 친수성의 유기 탄화수소 단량체를 미소다공성 필름의 미소기공 표면에 화학적으로 고착시킬때 (가)의 도포된 미소다공성 필름을 약1-10메가래드 정도의 이온화 방사선을 조사함으로서 보통 소수성의 폴리올레핀계 미소다공성 필름을 친수성으로 만들어 투수성을 개선하고 전기 저항을 저하시키는 방법.
