Head of the Laboratory: Prof. Sergey Vasil’evich Bronnikov, Doctor of Physical and Mathematical Sciences, Deputy Director for Science

 

Development of fundamental principles of formation of new conducting, membrane, adsorption-active polymer systems for a range of applications and strongly swelling hydrogels; studies of their structure and physico-chemical properties.

 

Lines of research:

• Development and optimization of the methods for preparation of microporous films of flexible-chain polymers with varying parameters (pore size, total porosity, specific surface area, permeability, mechanical properties).
• Strongly swelling pH-sensitive polyelectrolyte hydrogels, studies of gelation kinetics, swelling-contraction processes, mechanical properties.
• Multicomponent micro- and nanostructured composites including porous polyolefin films, conducting polymers, strongly swelling hydrogels, and natural polysaccharides.
• Development of novel biologically active membrane materials on the basis of bacterial cellulose.
• Separation-pervaporation membranes on the basis of the composites of poly(phenylene-iso-phthalamide) with C₆₀ fullerene and carbon additives; investigation of their physico-chemical, transport, and sorption properties.
• Study of phase transitions in thermotropic liquid crystal polymers by statistical analysis of polarized optical images using the corresponding computer software.
