本研究合成含磺酸基之聚苯醚(SPAEs)，並將磺酸基導入在側鏈上，首先經由親核性取代聚合反應合成Poly(arylene ether)s (PAEs)，以Chlorosulfonic acid為磺酸化試劑，直接將聚合物磺酸化，即可得到磺酸基位於側鏈上的SPAEs。
所合成的SPAEs，均可塗佈成具有韌性的薄膜，這些膜具有好的熱安定性與機械性質。其質子傳導度會隨著溫度增加而增加，在這研究所合成SPAEs，大部分它們的質子傳導度比Nafion 117高，在80℃，SPAE3系列 (IEC=1.73 mequiv./g)有最高的質子傳導度為338 mS/cm，約為Nafion 117 (188 mS/cm)兩倍，與同樣磺酸基都在側鏈上的類似結構比較，SPAEs系列具有相對低吸濕率、相對高質子傳導度的特性，其甲醇滲透率在1.32~5.93×10-7 cm2/s之間，都低於
Nafion 117 (16×10-7 cm2/s)，因這些含側鏈型磺酸基的SPAEs具有高質子傳導度、低甲醇滲透率和合理穩定性，因此有潛力成為直接甲醇燃料電池的質子交換膜材料。

A series of side-chain-type sulfonated poly(arylene ether)s (SPAEs) were prepared by polycondensation via a nucleophilic substitution reaction followed by post-sulfonation.
Tough and flexible films of the coplymers with good thermal and mechanical stability were obtained by solvent cast process in N,N-dimethylacetamide (DMAc) solution. Proton conductivities of coplymers increased gradually with increase in temperature. Most of SPAEs exhibited higher proton conductivity than Nafion 117. The highest proton conductivity of 338 mS/cm was obtained for SPAE3 coplymers (IEC=1.73 mequiv/g) at 80℃ among the tested SPAEs, which is higher than that of Nafion 117 (188 mS/cm). The SPAEs membranes exhibited high proton conductivity and low water uptake. In addition, the membranes exhibited low methanol permeability in the range of 1.32~5.93×10-7 cm2/s, which are much lower than that of Nafion 117 (16×10-7 cm2/s). Thus, these SPAEs could be the promising materials as alternative to Nafion membrane for direct methanol fuel cells applications because of them with high proton conductivity, low methanol permeability, and reasonable long-term stability.
