Nanocomposite Films of V_2O_5-MoO_3 Xerogel with Poly Ethylene Oxide Intercalation

摘要

Poly ethylene oxide (PEO)_x-V_2O_5 -MoO_3 (x = 0, 0.5, 1) films were prepared by the sol- gel method. The synthesis and structure of the films were investigated by XRD, TG-DTA, FTIR, etc. The results show that V_2O_5-MoO_3 xerogel has a layered structure and its interlayer space increased from 1.3181 nm at x = 0 to 1. 7898 nm at x = 1 after the nanocomposite films were dried, and PEO in the interlayer changes the interface structure by forming hydrogen bonds with V = O bands. CV measurement indicates that the intercalation of PEO improves insertion/ extration properties of Li~+ ions in the interlayer.
