Abstract：

A new solid polymer electrolyte PEI/Pebax2533/AgBF4 composite membrane is prepared with complexing method. By immersing the external surface of Pebax2533 layer of PEI/Pebax2533 composite membrane into AgBF4 solution, silver salt will transfer into Pebax2533 layer according to complexation with ether oxygen in Pebax2533 backbone, and a solid polymer electrolyte layer is formed. The silver salt content in the solid polymer electrolyte layer is dominated by the AgBF4 concentration. The increase of AgBF4 concentration enhances carrier facilitated transport of propylene, and lowers its plasticization effect. For PEI/Pebax2533/AgBF4 composite membrane prepared with 8.0mol/L AgBF4 solution, its selectivity for propylene and propane is above 1000, and the plasticization effect is suppressed completely.
