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.

Keywords: Electrochemical window, Ionic conductivity, Ionic liquid, Metalorganic framework, Polymeric membranes.
