The crosslinking films of poly(β-carboxyethylmethylsiloxane)—PEO and LiCF_3SO_3 complexes were prepared. The ionic conductivity of the poly(β-carboxy ethylmethylsiloxane)-Li~+ films was increased by complexing with PEO and that reached 10~(-5) S cm~(-1) at room temperature. And the effects of the molecular weight of PEO, content of PEO and crosslinking agent, concentration of LiCF_3SO_3, temperature on the ionic conductivity were investigated.
