The nanocomposite films were prepared by poly(ethylene oxide), PEO, intercalation in V_2O_5 xerogel in sol-gel. The synthesis and state of the films are in vestigated by the XRD, IR, SEM, etc. The results show that V_2O_5 xerogel is a layered structure which arranges in c-direction. The interlayer distance of V_2O_5 xerogel increases remarkably when PEO is intercalated in V_2O_5 xero gel interlayer. PEO has strong interaction with V_2O_5 host. The surface of the films is homogeneous without holes and cracks.
