Morphological properties of polymer electrolytes based on blends of polyethylene oxide and a perfluorinated polyphosphazene solvated with LiCF 3 SO 3 with and without the addition of dispersed γ‐LiAlO 2 are reported. The effect exerted on the morphology of the complex electrolytes by the addition of a plasticizer‐like propylene carbonate has also been studied. Results indicate the incorporation of γ‐LiAlO 2 leads to changes on the morphology of the complex electrolyte, as verified by X‐ray diffraction analysis. The major effect observed by plasticizer addition was a decrease on the crystallinity of the system together with a displacement of the T g towards lower temperatures. © 1998 John Wiley & Sons, Inc.
