Claims (1)

Способ получения пленочных полимерных нанокомпозиций обработкой полимерной композиции, состоящей из поливинилового спирта, воды и смеси водорастворимых солей трех- и двухвалентного железа, водным раствором щелочи при введении щелочи в количестве, по крайней мере, обеспечивающем полное протекание реакции щелочного гидролиза смеси солей железа с образованием смеси магнетита и магемита, отличающийся тем, что перед обработкой водным раствором щелочи полимерную композицию обрабатывают, по крайней мере, одним водорастворимым диальдегидом при рН 0 - 3 в присутствии кислоты в качестве подкисляющего агента.A method for producing film polymer nanocomposites by treating a polymer composition consisting of polyvinyl alcohol, water and a mixture of water-soluble salts of ferric and ferrous iron with an aqueous alkali solution when alkali is introduced in an amount at least that ensures the complete alkaline hydrolysis of the mixture of iron salts to form a mixture magnetite and magemite, characterized in that before treatment with an aqueous alkali solution, the polymer composition is treated with at least one water-soluble dialdehyde at a pH of 0 - 3 in the presence of acid as acidifying agent.
