Abstract
the conditions of formation and fields of application of the hybrid inorganic-organic complexes based on polyvinyl alcohol (PVA), variable-valence metals, polyacids, heteropolyacids and orthophosphoric acid are evaluated by rheological methods with regard for electrophysical, optical and sorption properties. The modification of hydrogen-bonded complexes with the applied electric, magnetic, thermal fields and sorption of water vapor changing the system of inter- and intramolecular hydrogen bonds are discussed. Evaluation is made of an influence of the type and concentration of components on the properties and structure of the complexes. The presence of sensitivity of the compositions to applied fields is related to formation acid of the structure- sensitive complexes between PVA molecules and metal ions Cu2+, Ni2+, Co2+, Fe3+ as well as the orthophosphoric acid or polyacids.
