文摘

Electrophysical parameters of polyvinyl alcohol (PVA) films comprising nanocluster molybdenum-based polyoxometalates (POMs), namely electrical conductivity, dielectric loss tangent, and dielectric permittivity, have been studied. Frequency and concentration curves have been plotted for these properties, which characterize the relaxation parameters of polymeric macromolecules and interactions of the polymer with spheroidal Keplerate POMs (Mo₁₃₂ and Mo₇₂Fe₃₀) and toroidal POMs (Mo₁₃₈).Original Russian Text © M.O.
