摘要:	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。此篇論文的是藉由液態核磁共振儀 (Solution NMR) 、 X光繞射儀 (XRD) 、微差掃描卡計 (DSC) 、熱重分析儀 (TGA) 、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6.80 × 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 onto the first two chlorides of the triazine ring in a stepwise manner at 0 and 25 oC, and then (3-aminopropyl)trimethoxysilane (APTMS) cross-linking to the third chloride site at 130 oC. Afterwards, (3-glycidyloxypropyl) -trimethoxysilane (GLYMO) react with the NH2 end groups of oligo(oxyalkylene)amines (Jeffamine-ED serious) and co-condensation with APTMS to form an organic-inorganic hybrid electrolyte system. The effects of several variables on conductivity were investigated, such as length of PEO chain, percentage of EO/PO segments, extent of cross-linking, and salt concentration (LiClO4). A full characterization was made by Solution NMR, X-ray Diffraction Spectrometer (XRD), Thermo Gravimetric Analyzer (TGA), differential scanning calorimetry (DSC), ionic conductivity, IR spectroscopy, and multinuclear solid-state NMR spectroscopy. The optimal lithium ionic conductivity for the hyperbranched copolymer electrolytes thus obtained reaches 6.80 x 10-5 S/cm at 30 °C with the composition of cc: ED2000: GLYMO = 1:3:3.
