Abstract
In this study, the distribution behaviors of the polystyrene sulfonic acid (PSSA) grafting polymer across the FEP-g-PSSA membranes prepared by a simultaneous irradiation method, were investigated by analyzing the cross-section of the membranes with a SEM-EDX instrument. The effects of irradiation conditions such as the degree of grafting, FEP film thickness, and grafting solvent on the distribution of the grafting polymer were mainly studied in this experiment. The results indicate that to obtain the evenly grafted FEP-g-PSSA membranes, the higher degree of grafting is required as the film thickness increases, and the lower dose rate are more effective than the higher dose rate at the given dose.

본 연구에서는 방사선 동시조사법에 의해 제조된 FEP-g-PSSA 막 단면을 SEM-EDX 기기로 분석하여 스티렌 술폰산 고분자(PSSA)의 막 내부로의 분포 경향을 연구하였다. 본 실험에서는 그래프트율, FEP 필름 두께, 선량률, 그래프팅 용매 등 여러 조사조건이 그래프트 고분자의 분포에 미치는 영향을 중점적으로 연구하였다. 실험 결과 균일하게 그래프트된 FEP-g-PSSA 막을 얻기 위해서는 필름 두께가 증가할수록 높은 그래프트율이 요구되어지고, 같은 조사 선량에서는 낮은 조사 선량률로 그래프트하는 것이 효과적임을 보여준다.
