초록

방사선 그래프팅 방법을 이용하여 다공성 PTFE 지지체에 친수성 고분자 사슬인 아크릴산 사슬을 도입시켜 강화 복합 연료전지막의 지지체로 사용하기 위한 PTFE 친수화 다공성 지지체를 제조하였고 FTIR을 이용하여 다공성 PTFE에 친수성 고분자가 성공적으로 도입되었음을 확인하였다. 제조된 지지체의 표면 친수화 정도를 관찰하기 위해 접촉각을 측정한 결과, 도입된 친수성 고분자 사슬이 증가할수록 소수성의 PTFE 표면 친수화도가 증가됨을 확인하였다. 또한 제조된 지지체의 물리화학적, 형태학적 특성은 FE-SEM, gurley number, 인장강도를 측정하여 관찰하였다.

In order to use as supporters for the reinforced composite fuel cell membrane, poly(acrylic acid)-grafted porous polytetrafluoroethylenes (PTFEs) were prepared via introduction of poly(acrylic acid) graft chains by a radiation grafting method. FTIR was utilized to confirm the successful introduction of poly(acrylic acid) graft polymer chains into the porous PTFEs. Contact angles were examined to observe the hydrophilicity of the surface of the prepared substrates. The result indicates that the hyrophilicity of the surface in the prepared substrates increases with an increase in the number of hydrophilic polymer chains. FE-SEM, gurley number, and tensile strength were also utilized to characterize the prepared substrates.
