摘要
Effects of nano-ceramic filler titanium oxide（TiO2） have been investigated on the ionic conductance of polymeric complexes consisting of polyvinyl chloride）（PVC）/poly（ethyl methacrylate）（PEMA）,and lithium perchlorate（LiClO4）.The composite polymer blend electrolytes were prepared by solvent casting technique.The TiO2 nanofillers were homogeneously dispersed in the polymer electrolyte matrix and exhibited excellent interconnection with PVC/PEMA/PC/UCIO4 polymer electrolyte.The addition of TiO2nanofillers improved the ionic conductivity of the polymer electrolyte to some extent when the content of TiO2 is 15 wt%.The addition of TiO2 also enhanced the thermal stability of the electrolyte.The changes in the structural and complex formation properties of the materials are studied by X-ray diffraction（XRD） and Fourier transform infrared spectroscopy（FTIR） techniques.The scanning electron microscope image of nano-composite polymer electrolyte membrane confirms that the TiO2 nanoparticles were distributed uniformly in the polymer matrix.
