摘要： Organic–inorganic hybrid electrolytes based on the reaction of tri-block copolymer poly(propylene glycol)- block -poly(ethylene glycol)- block -poly(propylene glycol) bis(2-aminopropyl ether), poly(ethylene glycol diglycidyl ether, and (3-glycidyloxypropyl)trimethoxysilane doped with LiClO 4 and SiO 2 nanoparticles were synthesized by a sol–gel process. The structural and dynamic properties of the materials thus obtained were systematically investigated by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, alternate current impedance, and 13 C solid-state NMR measurements. A maximum ionic conductivity of 3.2 × 10 −5 S cm −1 was obtained at 30 °C for the solid hybrid electrolyte with a [O]/[Li] ratio of 16 and 7 wt% of SiO 2 nanoparticles. A Vogel–Tamman–Fulcher-like temperature dependence of ionic conductivity was observed for the hybrid electrolytes, implying that the diffusion of charge carriers was assisted by the segmental motions of the polymer chains. 其他題名： Ionics 出版者： Berlin/Heidelberg: Springer Berlin Heidelberg 出版日期： 2014-11-01 出處： Ionics, 2014-11, Vol.20 (11), p.1561-1571 版權： Springer-Verlag Berlin Heidelberg 2014 識別號： ISSN: 0947-7047 識別號： EISSN: 1862-0760 識別號： DOI: 10.1007/s11581-014-1107-2
