| dc.description.abstract | 本研究利用有機反應合成一系列具有四醇基酮之聚醚醚酮高分
子，將直鏈結構之聚醚醚酮變化為交聯結構狀，並引進不同具有磺酸
基團之單體，期望將親疏水相分離，藉此得到最適合應用於燃料電池
的質子交換膜。
此一系列交聯高分子在不失去其優良的熱穩定性、物理性質與機
械強度情況下，交聯狀結構成功的降低了聚醚醚酮在高濕度下水膨潤
與尺寸變化率過高的情況，並在操作溫度 25oC 下可得到平均
10-2S/cm 的傳導度，並且於 70oC 高溫下更可進一步達到10-1S/cm
的表現。 其中 B-Np-SPEEKK 在 80oC 之熱水中，尺寸變化率只有
29% ， 並且傳導度更可達到 0.12S/cm 的水準。因此交聯狀聚醚醚
酮具有成為新型燃料電池之質子交換膜的潛力。

| dc.description.abstract | A series of branched and cross-linked poly(ether ketone)s were
synthesized by aromatic nucleophilic substitution reaction. The branching
and cross-linking were effective to improve the dimensional stability
under wet condition without losing their high thermal, oxidative, and
hydrolytic stability. The membranes exhibited high conductivity of 10-1
S/cm at 70oC、100% RH, and 10-2S/cm at 25oC、100% RH equally.
Especially B-Np-SPEEKK membrane exhibited low swelling ratio (29%
deformation), and exhibited high conductivity of 0.12S/cm at 70oC、
100RH. The results exhibited these branched and cross-linked ionomer
membranes are possible to become new type proton exchange membranes
in fuel cell.
