A new type dual‐phase polymer electrolyte (DPE) based on poly(MMA‐ g ‐NBR) and poly(methyl methacrylate) (PMMA) was prepared by film‐casting method. In the DPE, PMMA phase is selectively impregnated with the lithium salt solution, forming an ion‐conducting network, while poly(MMA‐ g ‐NBR) phase maintains mechanical strength in the system. With grafting effect, the compatibility of two phases (PMMA/poly(MMA‐ g ‐NBR)) can be enhanced obviously. The chemical and physical characteristics, morphology and ionic conductivity behavior of DPEs, and their interfacial stability between lithium metal electrode were characterized by using of FTIR, 1 HMNR, DSC, SEM, optical microscopic images, AC impedance, and linear sweep voltammetry. A new type DPE with good mechanics and high electrochemistry properties is obtained at an optimum proportion of two blending polymers. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
