Abstract

유연성이 우수한 세라믹 나노섬유 구조체, 광촉매 효율이 뛰어난 세라믹 나노섬유 분리막 및 이들의 제조방법이 제공된다. 본 발명의 일 구현예에 따른 세라믹 나노섬유 구조체는 제1 세라믹 성분 및 제2 세라믹 성분을 포함한다. 세라믹 나노섬유의 직경을 제어하여 나노섬유간 평균 기공 크기 및 최대 기공 크기를 조절하고, 제2 세라믹 성분을 투입하여 결정립 크기를 감소시킴으로써 유연성이 우수한 세라믹 나노섬유 구조체를 얻을 수 있다. 본 발명의 일 구현예에 따른 세라믹 나노섬유 분리막은 상기 세라믹 나노섬유 구조체 및 광촉매 무기 코팅층을 포함한다. 유연성이 우수한 세라믹 나노섬유 구조체 및 나노섬유 표면에 형성된 무기 광촉매 코팅층을 포함함으로써 유기물에 대한 광 분해능이 뛰어나고 장기간 분해 효율을 유지할 수 있는 분리막을 얻을 수 있다.
