Biskulova S. Spectral and electrochemical properties of the guest-host nanocomposites based on conducting polymers and oxides of vanadium and molybdenum.

The guest-host nanocomposites were prepared via direct intercalation of secondary doped polyaniline into the interlayer galleries of V2O5 and MoO3 nanoparticles, high conductivity at the level 10 Sm/sm of wich is caused by secondary doping of the polymer. It is established that the preparation conditions and polymer nature influence on spectral and electrochemical properties of the new class of host-guest hybrid nanocomposites, inside the interlayer galleries of V2O5 nanoparticles of which the macromolecules of polyethyleneoxide able to conduct ions as well as the conjugated polymer with electron-type conductivity (polyaniline, polypyrrole) are simultaneously located. It is shown the electronic structure of poly(2,5-dimercaptothiophene) and the interaction between the components of two- and tree-component nanocomposites based on poly(2,5-dimercaptothiophene), polyaniline and V2O5 determine stability during redox transitions at cycling of nanomaterials into the liquid organic electrolytes. The influenceof the nature of the intercalated polymers on the functional electrochemical characteristics (discharged capacity, cycling stability) and diffusion of lithium ion in three-component nanocomposites as potential cathode materials of lithium batteries is established. The diffusion coefficients of lithium ions into three-component nanocomposites based on conducting polymers (polyaniline, polypyrrole), polyethyleneoxide and V2O5 are by an oder of magnitude higher than in the xerogel V2O5.
