(IOP Publishing Ltd, 2023) Lebedev, V. V.; Miroshnichenko, D. V.; Kryvobok, R. V.; Cherkashina, A. M.; Riabchenko, M. O.
The possibility of designing mechanical properties of ceramic-inorganic polymer composites for protection against electromagnetic radiation is considered. As a result, the mechanical properties of polymer composite based on polyamide, modified with ceramic inorganic graphite-ferromagnetic fillers (silicon carbide, chromium oxide Cr2O3 and graphite) was received and optimized. The strength characteristics complex of ceramic-inorganic polymer composites with silicon carbide SiC, chromium oxide Cr2O3 and graphite content in diapason 5-15 % wt. were studied. It was established that the optimal strength characteristics can be received using binary modification of polyamide with ceramic-inorganic graphite-ferromagnetic fillers: polyamide 6 – SiC 10% wt. – Cr2O3 10% wt. and polyamide 6 – SiC 10% wt. – graphite 10% wt. Using mathematical modeling, it was established that the polyamide 6 – SiC 10% wt system is the most optimal for three-component complex modification with ceramic inorganic graphite-ferromagnetic fillers – Cr2O3 10% wt. – graphite 10% wt. By design experimental-statistical mathematical models in equal regressions, mathematical optimization of mechanical properties of polymeric ceramic-inorganic composites contains for protection against electromagnetic radiation was carried out. Designed polymer ceramic-inorganic composites for protection against electromagnetic radiation according to their strength characteristics can be used for modern radio absorbing materials production.

(ДВНЗ Український державний хіміко-технологічний університет, 2023) Lavrova, I. O.; Demidov, I. M.; Cherkashina, G. M.; Lebedev, V. V.; Zabiyaka, N. A.
The adhesive properties of brand BND 60/90 road bitumen with the oxidized phosphatide concentrate additive were studied. It was shown that the oxidized phosphatide increases the adhesive properties of bitumen brand BND 60/90. Oxidized phosphatide concentrate can be recommended as cost-effective alternative to expensive synthetic cationic surfactants, which are now widely used as adhesives for road bitumen. Based on the results of laboratory tests, the mathematical analysis of the obtained data was performed. Comparative graphs were plotted, and Pearson’s correlation coefficients and the approximation reliability values were calculated. It was found that the optimal composition for creating effective bituminous compositions with an increased thermo-physical and adhesive characteristics is 0.6 wt.% of oxidized phosphatide concentrate.

(2021) Skripinets, A.; Saienko, N.; Cherkashina, A. N.
The article presents a solution to practical problem - the development of epoxy coating of low combustibility with corrosion-resistant properties for the protection of glued-laminated timber in conditions of high humidity. Based on the test results obtained, it was found that when using the developed epoxy polymer protective coating, the resistance of wooden beams to distilled and seawater increases by more than two orders of magnitude, ensuring the integrity of wood products and structures, protecting the ends and not causing warping of the material. In conditions of medium aggressiveness of the environment i.e. 10% H₂SO₄, 10% NaOH, 10% NaCl, the application of the developed epoxy polymer coating to glued-laminated timber provides their high indicators of bio- and chemical corrosion protection (water resistance, resistance to sea water and aggressive aqueous solutions). The developed protective coating has fungicidal properties, protecting structures from the appearance of blue stains, mold and wood-destroying fungi. Revealed a good correlation between the concentration of biocide and fungicidal coating properties. A comprehensive assessment showed that the developed epoxy coatings have increased biocorrosion-resistant properties and can be used as protective coatings for glued-laminated timber structures exposed to mold fungi, high temperatures and high humidity.

The aim of the given work was to design new ecologically friendly polymer materials modified by derivatives of coal. An overview of the current trend in the development, production and application of efficient nvironmentally friendly polymer materials and composites is given. The main ways of hybrid modification of environmentally friendly polymeric composite for obtaining effective products based on them are presented. It is shown that it is promising to obtain environmentally friendly polymeric materials based on coffee waste using hybrid modifiers in the form of humic substances. Optimization studies have been conducted to determine the most effective composition of new environmentally friendly polymeric materials based on bioplastics "OK compost HOME" and coffee waste modified with humic substances. It was found that filling the bioplastic "OK compost HOME" with such coffee waste as coffee husk is more effective as with coffee grounds. It was found that the optimal content is 60 % mass coffee husk, that was modified by humic substances (2 % mass).

(IOP Publishing Ltd, 2023) Lebedeva, K. O.; Cherkashina, A. M.; Tykhomyrova, T. S.; Savchenko, D. O.; Lebedev, V. V.
Biologically active polymer hydrogel transdermal materials based on gelatin, sodium alginate, modified by humic acids, were designed and researched. Literature review was carried out and it was proved that humic acids using is perspective for the functional effect on the biologically active polymer hydrogel transdermal properties. It has been found that effective processes for receiving biologically active polymer hydrogel transdermal materials based on gelatin, hydroxypropyl cellulose and sodium alginate can be carried out in different humic acids concentration while achieving an effective increase in hydrogel polymers structuring processes. It can be seen efficiently increasing biologically active polymeric hydrogel transdermal materials based on gelatin and sodium alginate conditional viscosity and the specific electrical conductivity with an increase of humic acids content: from 114 to 135 sec and from 2350 to 2850 mkS/cm, respectively. Humic acids modification in biologically active polymeric hydrogel transdermal materials based on gelatin and sodium alginate caused structure formation with high density, and resistance and with larger agglomerates in hydrogels. It was found that the gelatin-based biopolymer hydrogels modification by humic acids makes it possible to receive biologically active polymeric hydrogel transdermal materials with higher swelling degree. It is shown that the application of new biologically active polymeric hydrogel transdermal materials based on gelatin and sodium alginate modified by humic acids allows improving the skin moisture-lipid balance. From the initial values of 34-36% moisture and 8-10 skin fat, they increase to 58-66% and 52-60%. So, designed polymer hydrogel based on gelatin, sodium alginate, modified by humic acids, are transdermal materials with good properties.

(Технологический центр, 2016) Rassokha, A.; Cherkashina, A.
The materials are designed and the properties are studied of the low viscosity furanepoxy reactive oligomers, structured by amine complex curing agents for the use as injection systems during the repairing and recovery construction work. A wide range of the amine containing structuring agents that have industrial potential and ensure a high degree of conversion was analyzed. This makes it possible to form the rational structure of furan epoxy polymers, which is due to the application of optimal parameters of structuring (temperature, concentration of ingredients, time and others) during the formation of the polymeric composition systems for construction purposes. The structure topological parameters were studied (traditional topological criterion of Wiener and others) and certain parameters of reactivity (structural functionality, formal unlimitedness, the index of distribution of electron density on the atoms of molecule, etc.) parent substances (monomers) during obtaining furan epoxy materials. The knowledge of this set of characteristics makes it possible to purposefully regulate structure and properties of the designed low viscosity injection furanepoxy polymeric materials. The deformation strength, adhesive, sorption, technological properties of the proposed low viscosity injection furan epoxy polymers for construction purposes were explored. As a result of the optimal combination of the set of structural topological parameters and technological factors, the high level of physical mechanical, adhesive properties, water resistance of the designed composite materials is ensured. The development of composite polymeric systems was accomplished with the use of the “green chemistry” principles.
Development and research of a label caseine adhesive for packaging the industrial and household products
(PC Technology Center, 2020) Cherkashina, A. N.; Rassokha, A. M.; Ryshchenko, I.; Komarova, O.
A new composition of the environmentally friendly water-based casein adhesive glue with the increased adhesion to the substrate (glass, polyethylene terephthalate, etc.) and the improved water resistance has been developed and explored. The glue is easily washed away when labeling products that are packaged in reusable containers, but, at the same time, possesses high adhesion to different surfaces. The optimal formulation for the developed glue adhesive composition based on casein has been determined with the help of the investigated properties. The effect of the amount of a modifying additive on the dynamic viscosity at different deformation rates, the stickiness of the adhesive composition, and the hydrogen ions index (pH) has been studied. Such technological properties of the glue adhesive composition were investigated as viscosity – 170 Pa∙s; pH – 7.21; the mass share of dry residue – 38.2 %; stickiness – 58.17 a.u.; working temperature – +20…+25 °С. The optimal technological parameters for using the glue have been defined: optimal viscosity, from 130 Pa∙s to 170 Pa∙s; temperature, 25 °C, and 35 °C, respectively. The adhesive strength between a paper label and glass is 4 points, polyethylene terephthalate – 3 points. The operation properties were assessed based on the resistance of the glue adhesive composition against changes in temperature and environmental conditions, humidity, and mechanical impact. The requirements for the glue adhesive have been stated that are to be taken into consideration in its operation: resistance against the condensed and icy water and the ability of the label to be removed from the surface of the container in a washing machine at a temperature of 70–80 °C. The glue adhesive composition was examined by a SAB Miller method to assess its quality during an ice water resistance test. A copy paper method was used to assess the label gluing quality. The requirements for the glue adhesive have been defined, which should be taken into consideration in its operation (the resistance against the condensed and icy water and the removal of a label in a washing machine at a temperature of 70–80 °C with the addition of NaOH or surface-active substances).
