The present invention relates to a conductive cross-linked film and a method for manufacturing the same. More particularly, the present invention relates to a conductive cross-linked film formed by cross-linking a high molecular weight polymer including an aromatic ring substituted with sulfonated polyarylene ether sulfone and sulfonate (-SO_3M), and a method for manufacturing the same. The conductive cross-linked film according to the present invention has excellent mechanical properties by improving dimensional stability, and has excellent water uptake and electrical conductivity. In addition, the method for manufacturing the conductive cross-linked film according to the present invention can easily adjust cross-linking density and proton conductivity, and thus a manufacturing method thereof is simple, so that the conductive cross-linked film can be manufactured very easily. 본 발명은, 전도성 가교막 및 그 제조방법에 관한 것으로, 특히, 술폰화 폴리아릴렌에테르술폰 및 술폰산염(-SO3M)이 치환된 방향족 고리를 포함하는 고분자 중합체가 가교되어 형성된 전도성 가교막 및 그 제조방법에 관한 것이다. 본 발명에 따른 전도성 가교막은 치수 안정성을 향상시켜 기계적 물성이 우수하면서도 워터 업테이크 및 전기전도성이 우수하다. 또한, 본 발명에 따른 전도성 가교막의 제조방법은 가교 밀도 및 양성자 전도도를 쉽게 조절할 수 있을 뿐만 아니라 제조방법이 간단하여 전도성 가교막을 매우 용이하게 제조할 수 있다.
