Structural organization, morphology and thermomechanical properties of triple polyelectrolyte-metal complex and derived nanocomposites.

The structural organisation of the triple polyelectrolyte-metal complexes based on nonstoichiometric polyelectrolyte complex with equimolar relation oppositely charged polyelectrolyte (pectin and polyethyleneimin) and transition metal ions (Me2+), and also nanocomposite, filling nanoparticle Cu2O or Ni0 investigates the complex of structural methods. It is established that in intermolecular space of all polymer-metal of systems there are metallo-polymeric complexes, thus transition from triple polyelectrolyte-metal complexes to nanocomposite is accompanied to reduction distances between layers of macromolecules, coordinated ions of metals. It is shown that as a result of chemical reduction cations metals Cu2+ or Ni2+ in triple polyelectrolyte-metal complexes there is a formation nanocomposite with the average size nanoparticle Cu2O 8 nanometers, and Ni0 -- 6 nanometers.
