ZnBDC-metal-organic framework (ZnBDC-MOF) has been synthesized by the solvothermal method by incorporating ionic liquid (IL) 1-butyl- 3-methylimidazolium tetrafluoroborate (BMIMBF4) at different wt%. The IL incorporated ZnBDC-MOF nanocomposites have been dispersed as composite nanofillers in poly (vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) to synthesize composite polymeric membranes. XPS has investigated differences in binding energies of Cu spin-orbit peaks upon the incorporation of IL. The structural features of the Zn metal nodes of ZnBDC-MOF based composite membranes have been analysed upon IL incorporation through scanning XANES and EXAFS. Temperature-dependent ionic conductivity and electrochemical window of the IL incorporated ZnBDC-MOF based PVdF-HFP composite electrolytes have also been investigated in this chapter to study the dynamics of ion transport in the composite polymeric membranes.
