초록
본 연구는 high impact polystyrene (HIPS)의 가교 및 술폰화시간을 달리하여 이온교환막을 제조하였다. 술폰화 HIPS (SHIPS) 이온교환막의 술폰화도는 술폰화시간이 증가함에 따라 증가하였고, 가교시간이 증가함에 따라 감소하였으며 이때 최대 술폰화도는 66%였다. 또한, SHIPS 이온교환막의 이온교환용량과 함수율은 가교율이 증가할수록 감소하였고 술폰화시간이 증가할수록 우수한 성능을 나타냈으며 가장 우수한 함수율과 이온교환용량은 35.2%와 1.55 meq/g이였다. SHIPS 이온교환막의 전기저항 및 이온전도도는 술폰화시간이 증가할수록 우수한 성능을 나타냈으며 가장 우수한 값은 각각 0.4 Ω·cm2와 0.1 S/cm으로 나타났으며 Nafion 117보다 성능이 우수하였다. SHIPS 이온교환막의 유기용매에서의 내구성은 가교시간이 증가할수록 증가하였으며 SEM 관찰 결과 술폰화시간이 진행됨에 따라 표면이 불균일하게 변화되는 것을 확인할 수 있었다.
In this study, ion exchange membranes were prepared using high impact polystyrene(HIPS) with various crosslinking and sulfonation time. Degree of sulfonation(DS) of sulfonated HIPS(SHIPS) membrane was increased with sulfonation time and decreased with crosslinking time. The highest value of DS was 66%. Also, water uptake and ion exchange capacity(IEC) of SHIPS membrane were decreased with degree of crosslinking and increased with sulfonation time. Then their values were 35.2% and 1.55 meq/g, respectively. Electrical resistance and ion conductivity of the membranes were showed more excellent value with sulfonation time. The maximum value of electrical resistance and ion conductivity were 0.4 Ω·cm2 and 0.1 S/cm, respectively. It is indicated that the SHIPS membrane has the higher performance compare with Nafion 117. Durability of SHIPS membranes in a organic solvent was increased with increasing crosslinking time. The surface roughness of HIPS membranes were confirmed with SEM that was become uneven sursurface with progressing sulfonation.
