- Аннотация: The structure and surface characteristics of SnO2 . 1.5H(2)O and composite materials with heteropolycompounds (HPC) formulated as SnO2 . 1.5H(2)O-HPC (where HPC = (NH4)(3)PW12O40 . nH(2)O, (NH4)(2)HPW12O40 . nH(2)O, and H3PW12O40 . nH(2)O) are studied by scanning tunneling microscopy. Hydrated tin oxide is characterized by a globular structure which differs substantially from the morphology of composite materials. The conductivity is studied as a function of both the temperature and humidity Of environment and the composition of composite materials. For composite materials containing ((NH4)(2)HPW12O40 . nH(2)O, the conductivity is shown to vary monotonously with the composition and obey the "mixture rule." Introduction of (NH4)(3)PW12O40 . nH(2)O to a composite is found to cause an extremely fast conductivity decay, whereas addition of H3PW12O40 . nH(2)O results in the appearance of a "plateau" on the conductivity vs. composition curve. The explanation given to the phenomena observed is based on the mechanism of protonic transport in heteropolycompounds.
