Abstract

아크릴로니트릴모노머를 전구체로하여 제올라이트를 함유한 부분활성화 PAN 복합체 섬유 를 제조하였다. 중량평균 분자량 630,000이고, 다분산지수가 1.30인 방사 dope를 건습식 사법(dry-jet wet spinning technique)으로 방사하였다. 제올라이트를 함유한 35-4Oμm두의 PAN섬유는 건습열 연신과정을 통해 배향도가 증가되었다. 같은 조건에서 얻어진 PAN섬유에 비하여 제올라이트를 함유한 PAN복합체 섬유는 89%의 인장강도를 나타내었다. 고리화와 부분활성화 상태는 적외선분광 분석법과 X선회절 분석법을 이용하여 확인하였다. PAN섬유의 부분활성화 이후에도 제올라이트의 함유에 따른 특성 피이크를 X선회절 분석법을 이용하여 확인할 수 있었다. 제올라이트를 함유한 PAN 복합체 섬유는 새로운 유무기 복합 흡착제로 사용을 기대할 수 있을 것으로 사료된다.

Partially activated polyacrylonitrile(PAN) composite fiber containing zeolite particle was prepared by using acrylonitrile(AN) as a precursor. Weight average molecular weight(Mw) and polydispersity index of spinning dope was 630,000 and 1.30 respectively. Dry-jet wet spinning technique was used for making PAN composite fiber. During the dry-jet wet spinning process, PAN composite fiber of 35-45 μm in diameter shows increased orientation. Initial elastic modulus of PAN composite fiber containing zeolite particles was 89% of PAN fiber at the same experimental condition. The cyclization and activated state of PAN fiber were confirmed by Fourier transform infrared(FT-IR) spectroscopy and X-ray incorporation of zeolite particles from XRD. Partially activated PAN composite fiber containing zeolite particles is expected to use as an organic-inorganic composite absorbent.
