Abstract:

The interaction between methanol vapors and composite film samples of polyvinyl alcohol-porous keplerate nanocluster polyoxomolybdate Mo-132 is studied by means of equilibrium interval sorption performed gravimetrically and using thermodynamic cycle calculations. Isotherms of methanol sorption by the films are obtained, and the concentration dependences of the average Gibbs energies of the interaction between methanol and films are calculated, along with the Gibbs energy and entropy of the interaction between polyoxometalate and the polymer. Micrographs of the studied composite films are presented.
