Synthesis and Characterization of Metal Organic Framework (cu-dub- BDC) and Study in the nanocomposite Polymer Electrolytes

Porous materials have been widely used in batteries and super capacitors attribute to their large internal surface area(usually1000-6000 m2. g1-) and porosity that can favor the electrochemicalreaction, interfacial charge transport ,and provide short diffusion paths for ions. Huge surface area high porosity, Low density, controllable structure and tunable pore size (1). In this study, a new filler ؛ metal-organic framework (MOF)(cu-dub-BDC) , via mechanical method (ball- mille)which is successfully prepared and incorporated in poly(methyl methacrylate) (PMMA) and lithium bis trifluoro methane sulfonylimide (LiTFSI) based nano composite polymer electrolyte (NCPE) by cast solution for improving electrochemical properties in lithium ion battery. Thecontrol of crystal and particle size is proven by powder XRD, SEM and dynamic light scattering (DLS) measurements. Thermo gravimetric analysis (TGA) and Ar sorption experiments show that the materials from modulated syntheses can be activated and that they exhibit high specific surface areas (2).
