PAMAM/[BMIM]PF6复合电解质的制备与性能

In this paper, the dendrimer/ionic liquid composite electrolyte was prepared by physical mixing mehtod, and its properties were systematically studied by using rheology, thermogravimetric analysis (TGA), and impedance analysis. Rheological tests show that the viscosity of the mixers significantly increased and viscosity reached the maximum when the ratio PAMAM/ionic liquid is 1:10. Thermal stability test shows that the thermal stability of the system increased gradually with the increase of the content of ionic liquids. The thermal stability of system is even higher than the pure ionic liquids when the ratio of ionic liquid/PAMAM excess 5:1. The ionic conductivity tests show that ionic conductivity increased gradually with the increase of the content of ionic liquids, and the ionic conductivity canreach 10-3 S/cm.
