摘要

摘 要
本研究以磷腈環單體N3P3Cl6為主體，利用鈉鹽法以烷氧化鈉取代其環上之氯，成功合成出可紫外光交聯之烯醚基磷腈化合物：N3P3(OC6H5)3(OCH2CH2OCH=CH2)3，V3P3。利用NMR、EA及FT-IR對化合物之結構進行鑑定，並進一步將所合成之V3P3添加計量之benzophenone(BPO)，經UV照射使之交聯，了解其交聯情形及離子間之作用力。另利用DSC了解交聯間熱轉移現象之變化(Tg)，並以TGA量測電解質之熱穩定性，選擇製備之最佳之條件。此外，將所合成之磷腈環化合物在不同計量之硫酸加以磺酸化後，及添加適當之benzophenone(BPO)，製備一系列固態高分子電解質polyelectrolyte，再以FT-IR鑑定磺酸化化合物之結構，及經UV照射後之交聯情形及離子間之作用力。另利用DSC了解熱轉移現象之變化(Tg)，以TGA觀察電解質之熱穩定性及使用交流阻抗分析法量測交聯後之高分子電解質之導電度。
由導電度結果顯示：室溫下,成膜固態交聯共聚物電解質在加入0.5 wt % 磺酸化試劑下，導電度可達1.3×10-6 S/cm，而黏稠之共聚物電解質5 wt%磺酸化試劑存在下，則可達6.0×10-3 S/cm，在高溫下，更可達到7.8×10-3 S/cm。

Abstract
In this thesis, a new UV curable vinylic ether-containing cosubstituted cyclotriphosphazene, N3P3(OC6H5)3(OCH2CH2OCH=CH2)3, V3P3 was successfully synthesized. This cosubtituted monomer has been characterized by a series of 1H, 13C, 31P NMR, EA and FT-IR spectroscopy studies. In addition, the corresponding sulfonated V3P3-based composite polymer electrolyte films were then prepared from V3P3 by sulfonating with various amount of sulfuric acid and curing with UV radiation using benzophenone (BPO) as a photo initiator. The degree of UV curing and the cation-oxygen interaction of the cured polymer electrolytes were investigated by FTIR spectroscopy. The ionic conductivities of the cured materials were measured by A. C. impedance analyzer. The conductivity of the as-prepared solid polymer electrolyte film with 0.5 wt% sulfonation reagent is 1.3×10-6 S/cm at room temperature. In contrast to the conductivity of the solid polymer electrolyte films, the best conductivity of the sticky polymer electrolyte film containing 5.0wt % sulfonation reagent is up to 6.0×10-3 S/cm.
