Scientific-and-educational group:
electrochemical methods of analysis and membrane separation

Area of research:
polymer membranes and nanocomposites: preparation, structure, transport properties; membrane processes: pervaporation, ultrafiltration, gas separation; thermodynamics and kinetics of nonequilibrium processes

Main results of applied work:

  1. The novel composites based on polyvinyl alcohol were developed together with the group of Nobel laureate Harold Walter Kroto (Florida State University, Tallahassee, Florida, USA). These composites contain polyhydroxy fullerenes with different degrees of hydroxylation that are C60(OH)22-24 and C60(OH)12. The method of composite preparation was developed. Composites characterization was carried out. It was shown that nonporous (diffusion) membranes based on polyvinyl alcohol had high retention capacity (selectivity) for water and high permeability. Two patents were obtained on a method of these diffusion membranes preparation and devices for their obtaining.

  2. Transport characteristics and physico-chemical properties of the novel membranes based on polyphenylene isophtalamide and poly (2,6-dimethyl-1,4-phenylene oxide) were studied. These membranes were modified by fullerene C60 and carbon nanotubes. It was shown that inclusion of carbon nanoparticles into polymer matrices increases the selectivity and permeability of membranes for the separation of a number of organic and water containing mixtures in pervaporation.
  3. Novel supported membrane was created with selectivity layer based on poly (2,6-dimethyl-1,4-phenylene oxide) that was cast on industrial porous Teflon support. This membrane was modified by 2% fullerene. It was found that efficiency of pervaporation removal of ester from esterification mixture increases by more than an order of magnitude with using this composite membrane. This is indicated the actuality of use of these membranes for the combined processes such as “reaction + pervaporation”.
  4. A new method was developed for producing a porous ultrafiltration membrane based on poly phenylene isophthalamide. This membrane was modified by various carbon nanoadditives (soot, fullerene, carbon nanotubes). The properties of the membrane and casting solutions were investigated. It was shown that membrane modified by fullerene has good anti-fouling stability. It is mean that membrane was not contaminated during filtration of different proteins, which prolongs their lifetime.
  5. The possibility of thermodynamic description of pervaporation process and approximation of experimental data in binary systems with the use of non-equilibrium thermodynamics relations was shown and confirmed based on experimental data and literature data. Prognosis of membrane selectivity in the process of pervaporation was developed.
