| Abstract | ||||
| This paper report the synthesis and properties of a series of composite polymer electrolytes formed by dispersion of tetraethylene glycol dimethyl ether (TEGDME) into poly (vinyl alcohol) complexed with magnesium salt. Scanning electron microscope (SEM) images of different TEGDME concentrations of films revealed that TEGDME dissocit the agglomeration of salt and some pores appers at the surface. The addition of TEGDME greatly enhances ionic conductivities of the electrolytes which is due to the high polarity and diffusivity of TEGDME. The optimum ionic conductivity value of the plasticized polymer electrolyte film of 1 wt.% TEGDME has been achieved to be of the order of 10-6 S.cm-1 at room temperature. Dielectric properties have been studied for different wt.% of plasticizer and their variations have been observed. | ||||
