Abstract
The fabrication of nano TiO2 polymer electrolyte of PVDF-HFP: Mg (ClO4)2 polymer matrix deploying solution casting technique. An effect of nano TiO2 with PVDF-HFP: Mg(ClO4)2 was studied by FTIR, and Electrochemical impedance spectroscopy. The FT-IR results revealed the dramatic changes in α, β, γ and δ polymorphous phase transition of –CF-CF- on PVDF-HFP polymer shows fair miscibility and interaction between Mg2+ ion and PVDF-HFP and nano TiO2; when nano TiO2 added to PVDF-HFP: Mg solid polymer electrolyte. The impedance spectroscopy results of PVDF-HFP: Mg(ClO4)2 with nano-TiO2 included revealed that bulk resistance decreased with increasing TiO2 nano filler concentration up to a specific optimum concentration, and then rose with additional increases in TiO2 nano filler concentration. The optimum conductivity was obtained for the PVDF-HFP:Mg(ClO4)2:TiO2(nano) solid polymer electrolyte in the 100:40:12 ratio, and the observed value is in the order of 10−3 Scm−1.
