Abstract

In this study, halogen element was introduced into polyphenylene oxide polymer using bromination reaction, and then halogen element was replaced with imidazolium. Imidazolium corporated polyphenylene oxide polymer was synthesized and the synthesis was confirmed by various instrumental characterization. In addition, gas permeation properties of $O_2$, $N_2$, $CO_2$ were studied with different imidazolium contents. As the content of imidazolium increased, the ion exchange capacity increased and the mechanical strength decreased. The gas permeance showed a tendency to decrease slightly with increaing imidazolium contents. Whereas, it was confirmed that the tendency of $CO_2/N_2$ ideal selectivity increased as the imidazolium contents increased.

본 연구에서는 폴리페닐렌옥사이드 고분자에 브롬화반응을 통해서 할로겐 원소를 수월하게 도입하고, 도입한 할로겐 원소를 이미다졸륨으로 치환하여 이미다졸륨이 도입된폴리페닐렌옥사이드를 합성하였다. 다양한 특성평가를 통해서 합성이 이루어졌음을 확인하였고, 산소, 질소, 이산화탄소 기체투과 특성평가를 진행하여 합성한 고분자의 기체특성을 확인하였다. 이미다졸륨의 함량이 증가할수록 합성고분자의 이온교환용량이 증가하였으나, 기계적 강도는 감소하였다. 특히, 기체투과도는 미세하지만 감소하는 경향을 나타내었으며, 이산화탄소/질소 선택도의 경우 이미다졸륨 함량이 높아질수록 증가하는 경향을 확인할 수 있었다.
