Abstract: Double ionic conducting AB crosslinked polyether solid electrolytes(ABCPE2)and electrorheological(ER)fluids based on ABCPE2 were synthesized by solution polymerization or inverse suspension polymerization of α,ω bismethacryloyl capped poly(ethylene oxide), which has been mixed with LiClO 4. Ionic conductivity of ABCPE2 as well as ER effect and electric current density of ER fluids based on ABCPE2 were studied, in the meantime, the shape and sizes of particles in the ER fluids were observed with scanning electronic microscopy. As a result, ABCPE2 with high ionic conductivity of 8.0×10-5 S/cm(25℃)was obtained as well as ER fluid with relative high activity.

Key words: poly(ethylene glycol), AB crosslinked polyether, electrorheological fluid, solid electrolyte
