The effect of different plasticizers on the properties of PAN-LiCF(3)SO(3) polymer electrolytes has been studied. Propylene carbonate (Pc) and ethylene carbonate (EC) having different values of donor numbers, dielectric constant and viscosity have been used as plasticizers. The highest room temperature conductivity for the film in the PAN-LiCF(3)SO(3) system was 3.04 x 10(-4) s cm(-1). The highest room temperature conductivity for the films in the PAN-EC-LiCF(3)SO(3) system and the PAN-PC-LiCF(3)SO(3) system was 1.32 x 10(-3) and 8.64 x 10(-4) S cm(-1). The addition of plasticizers has been found to enhance the conductivity of polymer electrolytes by increasing the amorphous content …
Comparative Studies On Plasticized And Unplasticized Polyacrylonitrile (Pan) Polymer Electrolytes Containing Lithium And Sodium Salts, Zurina Osman
Zurina Osman
Polymer electrolytes based on polyacrylonitrile (PAN) containing inorganic salts; lithium inflate (LiCF(3)SO(3)) and sodium triflate (NaCF(3)SO(3)) and ethylene carbonate (EC) as plasticizer were prepared using solvent casting technique. In this study, five systems of plasticized and unplasticized polymer electrolyte films i.e. PAN-EC, PAN-LiCF(3)SO(3), PAN-NaCF(3)SO(3) PAN-EC-LiCF(3)SO(3) and PAN-EC-NaCF(3)SO(3) systems have been prepared. The structural and morphological properties of the films were studied using infrared spectroscopy and scanning electron microscopy (SEM) while the conductivity study was done by using impedance spectroscopy. The infrared results revealed that interaction had taken place between the nitrogen atoms of PAN and Li(+) and Na(+) ions from …
