Abstract

In this study, several poly(styrene-co-(trimethoxysilyl)propyl methacrylate)-grafted ETFE films were prepared by a simultaneous irradiation grafting method. After mixing of styrene/(trimethoxysilyl)propyl methacrylate(TMSPM) monomers with various solvents, the effects of various irradiation conditions such as total dose, dose rate and monomer concentration on the degree of grafting of the prepared membranes were investigated. Results indicated that the higher degree of grafting was obtained when acetone was used as a solvent. The formation of poly(styrene-co-TMSPM) grafts on the ETFE films was verified using FTIR spectrometry and the distribution of the poly(PTMSPM) graft polymer over the cross-section of the grafted film was confirmed using SEM-EDX instrument.

본 연구는 스티렌과 (trimethoxysilyl)propyl methacrylate(TMSPM)을 함유하여 그래프트된 ETFE 필름을 방사선 동시 조사방법으로 제조하는 것에 관한 연구이다. 스티렌/TMSPM을 혼합한 물질을 여러 종류의 용매를 사용하여 일정한 비율로 희석 후 조사선량, 조사선량률 및 희석된 용액의 농도 등의 조건을 달리하여 그래프트율에 미치는 영향을 관찰하였다. 그 결과 스티렌/TMSPM 단량체 혼합물에 아세톤 용매를 사용한 경우에 다른 용매를 사용한 것보다 높은 그래프트율을 보여주고 있음을 알 수 있었다. IR 스펙트럼 분석을 통하여 스티렌과 TMSPM이 동시에 ETFE 필름에 그래프트됨을 확인할 수 있었으며 SEM-EDX를 통하여 PTMSPM이 함유하고 있는 실리콘 분포도를 분석한 결과, PTMSPM 그래프트 고분자가 ETFE 필름 내부까지 균일하게 그래프트가 이루어졌음을 관찰할 수 있었다.
