Specific Features of the Structural Organization and Thermomechanical Properties of Pectin–Ag0–P4VP Nanocomposites Formed Under the Action of Constant Magnetic Field

Materials Science Aims and scope

By using a complex of structural methods and thermomechanical analysis, we study the influence of constant magnetic field on the specific structural features and thermomechanical properties of pectin–Ag0 –P4VP nanocomposites. By the methods of X-ray diffraction analysis, it is demonstrated that, in the course of chemical reduction of Ag+ cations in polyelectrolyte-metal complexes under the action of a constant magnetic field, a nanocomposite is formed on the basis of pectin–P4VP polyelectrolyte complex and Ag0 nanoparticles but with a higher content of metallic silver than in the absence of magnetic fields. It is shown that, under the action of the field, silver-containing nanocomposites are formed with much higher temperatures of glass transition and lower temperatures of transition into the viscous state. These composites are also more susceptible to relative deformation.
