Main Results of Applied Work

  1. In the framework of the collaboration with the group of Nobel laureate Harold Walter Kroto (Florida State University, Tallahassee, Florida, USA) the novel composites based on polyvinyl alcohol were developed. 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. Also, articles were published in highly rated journals on this research topic.
  2. In the framework of the collaboration with the membrane group of Denis Roizard (University of Lorraine, Nancy, France), composite membranes with a thin selective layer based on polyvinyl alcohol (PVA) and PVA/fullerenol composites were developed and studied using various cross-linking methods during the pervaporation dehydration of industrially significant solvents (tetrahydrofuran and acetic acid).
  3. In the framework of the collaboration with the membrane group of Denis Roizard (University of Lorraine, Nancy, France) and the Christian Serre group (Lavoisier Institute, Versailles, France), dense and composite PVA membranes modified with MOF ZIF-8 functionalized by chains of polyethylene glycol (PEG) for better dispersion of particles in the polymer matrix. It was shown that the creation of the composite PVA membrane and the introduction of ZIF-8-PEG into its matrix leads to an increase in the permeation flux in 11 times while maintaining a high separation factor compared to an unmodified PVA membrane.
  4. Transport characteristics and physico-chemical properties of the novel membranes based on polyphenylene isophtalamide 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 binary methanol containing mixtures in pervaporation.
  5. 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".
  6. A new method was developed for the preparation of pervaporation and ultrafiltration membranes based on polyphenylene isophthalamide and polysulfone modified with Pluronic F127. The properties of membranes and casting solutions were studied. It was shown that the introduction of Pluronic F127 into the polymer matrix leads to an increase in pore size for ultrafiltration membranes and to an increase in the free volume for pervaporation membranes, as well as to an increase in permeation flux and surface hydrophilization for two membrane types.
  7. 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.
  8. A new composite based on polyvinyl alcohol modified with carboxyfullerene was developed. A method for its preparation was developed and characterization was carried out. It has been shown that non-porous membranes based on polyvinyl alcohol have high selectivity with respect to water, high permeability and stability during ethanol dehydration.
  9. A method for modifying polysulfone with fullerene was developed and the transport characteristics of the obtained composites were studied during the pervaporation of an ethyl acetate-water mixture. It was shown that the modification of polysulfone by fullerene leads to surface and inner modification of the membrane and, as a result, to an improvement in permeability.
  10. New composite membranes based on polyvinyl alcohol were developed using bulk modification (introduction of fullerenol , сhitosan and polyaalylamine hydrochloride) and surface (Layer-by-layer assembly of polyelectrolytes: sodium polystyrenesulfonate, chitosan, polyallylamine hydrochloride, polyacrylic acid) modification. It was found that the combined use of bulk and surface modifications led to a significant increase in the permeation flux with a high water content in permeate. The permeation flux of the developed membrane exceeded 8.5 times the permeation flux of the commercially available analogue Sulzer PervapTM 1201 membrane with comparable selectivity.
  11. In collaboration with the membrane laboratory (the head is professor I.V. Vorotyntcev) of Nizhny Novgorod State Technical University R.E. Alekseeva were synthesized copolymers of chitosan with acrylonitrile and styrene to improve chemical and mechanical stability. Composite membranes with a selective layer based on chitosan copolymers deposited on a commercial UPM-20 substrate were developed. The developed membranes were studied by various physicochemical methods of analysis. Transport properties were studied during dehydration of tetrahydrofuran. It was shown that the membrane with a selective layer based on the copolymer chitosan-polyacrylonitrile had the optimal transport characteristics.
