Abstract:	摘要： Organic–inorganic hybrid electrolyte membranes based on poly(propylene glycol)-block-poly(ethylene glycol)-block-poly(propylene glycol) bis(2-aminopropyl ether) complexed with LiClO4 via the co-condensation of tetraethoxysilane (TEOS) and 3-(triethoxysilyl)propyl isocyanate have been prepared and characterized. A variety of techniques such as differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, alternating current (AC) impedance and solid-state nuclear magnetic resonance (NMR) spectroscopy are performed to elucidate the relationship between the structural and dynamic properties of the hybrid electrolyte and the ion mobility. A VTF (Vogel-Tamman-Fulcher)-like temperature dependence of ionic conductivity is observed for all the compositions studied, implying that the diffusion of charge carriers is assisted by the segmental motions of the polymer chains. A maximum ionic conductivity value of 5.3 × 10−5 Scm−1 is obtained at 30 °C. Solid-state NMR results provide a microscopic view of the effects of salt concentrations on the dynamic behavior of the polymer chains. 其他題名： Membranes (Basel) 出版者： Switzerland: MDPI AG 出版日期： 2012-06-13 出處： Membranes (Basel), 2012-06, Vol.2 (2), p.253-274 資源來源： Publicly Available Content Database (Proquest) 版權： Copyright MDPI AG 2012 版權： 2012 by the authors; licensee MDPI, Basel, Switzerland. 2012 識別號： ISSN: 2077-0375 識別號： EISSN: 2077-0375 識別號： DOI: 10.3390/membranes2020253 識別號： PMID: 24958176
