Experimental studies of morphology, supramolecular structure, and phase transformations in nano- and microstructured polymer materials and supramolecular systems by X-ray analysis, transmission and scanning electron microscopy, atomic force microscopy, polarized light microscopy, differential scanning calorimetry, thermogravimetry, and UV spectroscopy.

 

Lines of research:

 

• Study of morphology, supramolecular structure and phase transitions in nano- and microstructured polymer materials and supramolecular systems by X-ray structural analysis, transmission and scanning electron microscopy, atomic force microscopy, polarized light microscopy, differential scanning calorimetry, thermogravimetry, and UV spectroscopy.
• Development of methodology of studying the structure-property relationship in hybrid organic-inorganic nanosystems based on metal and metalloid nanoparticles stabilized with water-soluble polymers.
• Study of the structure and sorption properties of promising biomedical materials: gel films of bacterial cellulose intercalated with nanoparticles of various natures stabilized with polymers and hydrated calcium phosphates.
• Study of structure, morphology, and thermal properties of the nanocomposites intended for membrane technologies based on thermostable polymers filled with nanoparticles of different chemical natures.
• Study of structure and thermal properties of supramolecular inclusion complexes (polyrotaxanes and pseudopolyrotaxanes) on the basis of cyclic and linear polymers.
• Study of supramolecular structure and thermo-mechanical properties of porous polyethylene and poly(vinylidene fluoride) films; investigation of conducting composites based on these polymers and polyaniline (polypyrrole) at all stages of production (extrusion, annealing, orientational drawing, thermofixation).
