고분자 전해질형 연료전지용 나프탈렌 부분을 갖는 술폰화된 폴리(아릴렌 이써 설폰) 블록 공중합체의 합성과 특성연구 = Synthesis and Properties of Sulfonated Poly (Arylene Ether Sulfone) Block Copolymers with Naphthalene Moiety for Polymer Electrolyte Fuel Cells

다국어 초록 (Multilingual Abstract)

In this study, sulfonated PAES block copolymers have been synthesized via nucleophilic substitution reaction. Hydrophobic oligomer was prepared using 2,6-dihydroxynaphthalene and bis(4-chlorophenyl) sulfone, whereas hydrophilic oligomer was prepared using sulfonated bis(4-chlorophenyl) sulfone and bis(4-hydroxyphenyl) sulfone. The chemical structure of polymers was analyzed by $^1H$ NMR, FT-IR and GPC. The thermal properties of polymers were measured by TGA and DSC. The oxidative stability of membranes was investigated by Fenton's test. Furthermore, the proton conductivity of membrane was found to be 26 mS/cm at $90^{\circ}C$. All physiochemical properties suggest that fabricated membrane have a great potential for applications in PEMFC.
