Abstract
본 발명은 고분자 합성 수지 상에 원적외선 방사 세라믹을 침적시켜 기체 및 액체의 정화 및 분리에 사용되는 세라믹 분리막 및 그의 제조방법에 관한 건이다. 산화망간, 산화동, 산화철, 2가 및 3가 철의 금속촉매를 금속으로서 0.1 내지 5중량% 함유하는 원적외선 방사 세라믹이 폴리우레탄 수지와 함께 폴리에틸렌 부직포에 침적되고 키토산으로 코팅후 고정화된 것을 특징으로 하는 세리믹 분리막은, 물이나 유기용제에 안정하고 높은 기계적 인장 강도를 가지면서도 친수성이므로 하수 및 오염공기로부터 고분자 화합물, 유기 화합물 및 중금속 산화물 등을 선택적으롱 분리시킬 수 있으므로, 공기를 여과 및 정화할 뿐 아니라, 하수 및 폐수를 정화하고 경수를 연화하는 데에도 다양하게 사용할 수 있으며 재사용이 가능하다는 장점이 있다.
