Abstract: Two kinds of poly(ethylene oxide) (PEO800 and PEO2000) macromer, which have different functionalities, were synthesized and polymerized in the presence of LiClO4 to form so-called “graft polymer network”.The PEO800 networks were completely amorphous and showed quite good ambient ionic conductivity (σ298K = 4.8×10-5 S · cm-1).However, the PEO2000 networks were crystalline and the conductivities for these polymer networks were lower than that of PEO800 systems.The relationship between the structure and morphology as well as the conductivity for those graft polymer networks has been discussed.
