摘要：
A correlation is found between the proton spin-spin relaxation times in gold nanocomposites based on arabinogalactan in aqueous solutions and the maximum conducting layer thicknesses of films cast from solutions of composites. The obtained correlation is considered from the viewpoint of electrization's effect on the mobility of macromolecules of the investigated polymer nanocomposites. The dependence of arabinogalactan mobility on the type of solvent (H2O or D2O) is established, and a conclusion is drawn as to the effect of the hydrogen bonds of arabinogalactan with solvent on polymer mobility in solutions.
