Abstract:	此篇論文主要是利用 jeffamine-ED serious 與三聚氯氰反應形成具有星狀結構之高分子，進一步藉由添加3-Glycidyloxypropyl trimeth- oxysilane (GLYMO) 使其固化，觀察在不同 Lithium perchloride (LiClO4) 濃度下對導電行為的影響。此篇論文的是藉由X光繞射儀 (XRD) 、微差掃描卡計 (DSC) 、紅外吸收光譜儀 (FTIR) 、交流阻抗分析儀 (AC-Impedance) 以及固態核磁共振光譜儀 (Solid State NMR) 等儀器對具有星狀結構之的固態高分子電解質加以分析研究。藉由交流阻抗分析儀的分析結果，發現於乾式固態高分子電解質中，其導電度隨高分子鏈段運動性增加而上升。在30 ?C 時的最佳導電度可達4.36 × 10-5 S/cm。 A sol-gel synthetic route for preparing poly(oxyalkylene) block copolymers has been developed by using 2,4,6-trichloro-1,3,5-triazine (cyanuric chloride, cc) as the coupling core. The coupling reaction involves the selective substitutions of oligo(oxyalkylene)-amines at 0?C, 25?C and 130?C. Afterwards, (3-glycidyloxypropyl)-trimethoxysilane (GLYMO) reacts with the NH2 end groups of oligo(oxyalkylene)amines (Jeffamine-ED serious), and then the Si-OCH3 will condensation with other GLYMO. The effects of several variables on ionic conductivity were investigated, such as length of PEO chain, percentage of EO/PO segment, extent of cross-linking, and salt concentration (LiClO4). Characterization was made by solid-state NMR, Differential scanning calorimetry (DSC), AC-Impedance and IR spectroscopy. The optimal lithium conductivity for the copolymer electrolytes thus obtained reaches 4.3 x 10-5 S/cm at 30?C.
