摘要：A poly(ethylene oxide) (PEO) 400 macromer has been synthesized and used as a crosslinking agent to crosslink two kinds of unsaturated polyester having PEO 400 (polyester I) or PEO 600 (polyester II) segments in polyester chains and containing LiClO4. For polyester I and II networks, the conductivity, sigma = 6 x 10(-6) and 2 x 10(-5) S cm-1, respectively, at ambient temperature. The glass transition temperatures of the systems were also measured using differential scanning calorimetry and were found to be very similar (229-232 K). The high ambient conductivity for these networks was therefore attributed to the formation of a 'graft network' in which most of the macromers exist as grafts, thereby enhancing ionic conductivity.
