STUDY ON ION CONDUCTION BEHAVIOR OF THE PLASTICIZED POLYMER ELECTROLYTES BASED ON POLY(METHYLMETHACRYLATE-CO-ALKALI METAL METHACRYLATE) BY FT-IR SPECTROSCOPY

The ion conduction behavior of the plasticized polymer electrolyte bas ed on poly(methylmethacrylate-co-sodium methacrylate) was studied with in-situ FT-IR technique under a de electric field. This study include s a detailed investigation on the various environments of the plastici zer EC in the ionomer electrolyte. The transport of-charge carrier in the ionomer electrolyte was strongly dependent on the ion content of t he ionomer and the ionic aggregates were formed in the ionomer electro lyte with around 7 mol% content of the ionomer. From the in-situ FT-IR experiments the transference number could be also calculated. (C) 199 8 Published by Elsevier Science Ltd. All rights reserved.
