| Popis: | PVDF polymer, LiClO4 salt doped PVDF polymer electrolyte, PVDF/PEG polymer blend and LiClO4 salt doped PVDF/PEG polymer blend electrolyte thin films prepared via solution cast method further these prepared thin films undergone with different characterization techniques i.e. XRD, FTIR, SEM and DSC. XRD and SEM results confirmed that reduction in crystalline nature of PVDF polymer in the presence of PEG polymer and LiClO4 salt. FTIR spectra results revealed that complexation/interaction of LiClO4 salt with polymers. Shifting of glass transition temperature (Tg) and disappearance of melting temperature(Tm) on the DSC curves of PEG and LiClO4 salt doped thin films was observed, which indicated that thermal stability and reduction in crystalline nature of thin films. These results confirmed that LiClO4 salt doped PVDF/PEG thin films may offer higher ionic conductivity for the fabrication of electrochemical cell. |
