Research Activities

Layered silicates:

  • Intercalation and grafting of layered inorganic structures with organic and metal-organic molecules, ions and complex ions.
  • Synthesis of organometallic complexes, nanoparticles of metals, metal oxides and metal sulfides in nanoreactor of inorganic host matrices.
  • Surface modification of inorganic matrices first of all layer silicates by anchoring of nanoparticles (metals, metal oxides and metal sulfides) grown directly on the silicate matrix.
  • Nanocomposite coatings on the silicate matrix are prepared by gradual deposition of various types of nanoparticles on the silicate surface.
  • Preparation of polymer-silicate-carbon nanocomposites by intercalation and delamination of silicate matrices.
  • Nanoparticles for various types of nanocomposites are prepared by mechanical and chemical methods (chemical and electrochemical etching, chemical delamination of layered structure via intercalation) combined with microwave field. Milling and grinding of materials is carried out by dry jet milling, cryo-milling and hard materials grinding combined with microwave field. Nano/micro-particles are characterized with laser particle size analyzer, using dynamical light scattering.
