Investigations into solid polymer electrolytes have been motivated due to their interesting physics and wide application potentials in high energy density batteries and electrochemical devices. Although it has these advantages, there is a major drawback of relatively low ionic conductivity at room temperature. Recently, to produce electrolytes that possess high ionic conductivity and maintain sufficient performance is to prepare nanocomposite solid polymer electrolytes. In this work, we made an attempt to prepare PVDF-based nanocomposite solid polymer electrolytes using organo-clay as nanofiller and examined the changes of crystalline structure in accordance with the content of clay. First of all, XRD and DSC were applied to analyze the samples. From these measurements, we verified the degree of cystallinity for each sample. Also, we confirmed the changes of nanocomposite structures visually by TEM and ionic conductivity was decided with ac impedance measurement. |
