초록
본 연구에서 염화비닐벤질(vinylbenzyl chloride) 단량체는 동시조사방법을 이용하여 poly(tetrafluoroethylene-co-hexafluoropropylene)(FEP), poly(tetrafluoroethylene-co-perfluoropropylvinyl ether)(PFA), poly(ethylene-co-tetrafluoroethylene)(ETFE) 불소고분자 필름에 성공적으로 그래프트되었다. 실험 결과 같은 조사조건을 적용할 경우 다른 불소고분자 필름보다 ETFE 불소필름에 PVBC 고분자가 쉽게 그래프트됨을 확인하였다. 그래프트된 필름들은 FTIR, TGA, SEM-EDS 기기들을 사용하여 분석하였다. 그래프트된 필름의 파단신장률은 그래프트률이 증가할수록 감소되는 것을 확인하였으며 ETFE에 그래프트된 필름은 다른 불소고분자에 그래프트된 필름들과 비교하여 더 좋은 기계특성을 가지고 있음을 확인하였다.
In this study, a vinylbenzyl chloride (VBC) monomer was successfully grafted onto the several fluoropolymer films including poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP), poly(tetrafluoroethylene-co-perfluoropropylvinyl ether) (PFA), and poly(ethylene-co-tetrafluoroethylene) (ETFE) films by using a simultaneous irradiation method. The results indicated that PVBC graft polymer can be easily grafted onto the ETFE film than other fluorinated films under the same irradiation condition. The grafted films were characterized by using FTIR, TGA, and SEM-EDS instruments. The elongation at the breaking of the grafted films was found to decrease with an increase of degree of grafting (DOG). The PVBC-grafted ETFE films were found to have better mechanical properties than other PVBC-grafted fluorinated films.
