摘要

正

The polysiloxane containing propylene carbonate side group and several lithium poly-meric salts were synthesized. The structure were confirmed by IR

NMR and XPS. Theblending systems of polysiloxane containing propylene carbonate group with different lithiumpolymeric salts were studied by ion conductivity XPS and DSC. Different lithium poly-meric salts in the blending system lead to conductivity arranged in the following sequence:poly（lithium ethylenebenzene sulfonate methylsiloxane）

poly（lithium propionate methyl-siloxane）

poly（lithium propylsulfonate methylsiloxane）

poly（lithium styrenesulfonate）.In the blending system the best single ion conductivity was close to 10

-5

Scm

-1

at roomtemperature. XPS showed that at low lithium salt concentration the conductivity increasedwith the increasing content of lithium salt

in consequence of the increase of free ion andsolvent separated ion pair. At high lithium salt concentration the free ion was absent andthe solvent-separated ion pair functioned as carrier.
