Abstract
With the aim of developing solid electrolytes with high ionic conductivity, PVdF-HFP has been blended with a triblock copolymer (poly(propylene glycol)-block-poly(ethylene glycol)-poly(propylene glycol) bis(2-aminopropyl ether); ED2003), SiO2 nanoparticles (with modified morphology) and electrolyte solution (1 M LiBF4 in EMIMBF4) in different proportions. The addition of ED2003 has resulted in enhancing the porosity of the polymer matrix and eventually the ionic conductivity. Electrolyte films with SiO2 nanoparticles having a modified morphology enhance both the polymer-filler interface and the electrochemical properties as compared to the films with the spherical SiO2 nanoparticles, thus enhancing the ion conduction. Ionic conductivity of ∼0.274 mScm−1(at 30ºC) has been obtained for the electrolyte film with 30 wt.% of electrolyte solution and a minimal amount (1 wt.%) of modified SiO2 nanoparticles. Also, 1H and 13C NMR studies of the electrolyte films have been done to understand the chemical surrounding and the interaction of ionic liquid's cation (EMIM+) with the other constituents of the matrix.
