Abstract:

The physicochemical characteristics of solutions intended for preparing composites that contain a water-soluble polymer, polyvinylpyrrolidone (PVP), and nanocluster polyoxometalates (POMs) based on molybdenum with Keplerate (Mo-132 and Mo72Fe30) and toroidal structure (Mo-138) are studied. Concentration dependences of the kinematic viscosity of solutions upon changes in the absolute and relative contents of the polymer component are obtained along with the frequency dependences of the dielectric loss tangents of such solutions that correlate with them. The data allow us to confirm the composition of POM-polymers associates that form, and to estimate the relaxation parameters of ions in solutions.
