Ceramic-inorganic polymer composites for protection against electromagnetic radiation mechanical properties designing
(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.

(РС Теshnology сentеr, 2023) Lebedev, Vladimir Vladimirovich; Miroshnichenko, Denis Viktorovich; Tykhomyrova, Tetyana Sergiivna
Object of article study is lignite humic acids hybrid modification technology of biodegradable films based on polyvinyl alcohol. The possibility of increasing the strength and operational properties of biodegradable polymeric materials based on polyvinyl alcohol by using its modification with the different types of humic acids from lignite is considered. Lignite humic acids hybrid modification films with antibacterial properties were obtained. The twostage technology of lignite humic acids hybrid modification of biodegradable films based on polyvinyl alcohol was formalized. At the first stage of lignite humic acids hybrid modification technologies for hybrid-modified biodegradable materials production, lignite humic acids are received. At the second stage, hybrid modification of lignite humic acids (that are part of biodegradable polyvinyl alcohol films), which are received by watering from a solution, takes place. It has been conducted a study on determining the effect of lignite humic acids hybrid modification on the most important operational properties of biodegradable film based on polyvinyl alcohol, i. e., tensile strength, relative elongation at break and time of mold appearance. Changes in tensile strength, relative elongation at break and time of mold appearance for the lignite humic acids hybrid modified biodegradable polymeric materials based on polyvinyl alcohol were revealed depending on the content of the different types of lignite humic acids. It was also shown that the lignite humic acids hybrid modification of polyvinyl alcohol with the different types of humic acids allows preserving the biodegradability of the films along with imparting the antibacterial properties. The developed lignite humic acids hybrid modified biodegradable polyvinyl alcohol films with antibacterial properties, in terms of their operational characteristics, are superior to the known similar bio degradable films based on natural biopolymers.

Researching on brown coal humic substances hybrid modification of biodegradable materials based on pol ylactide and coffee waste for their sorption resistance in different liquid mediums are carried out in this work. The objects of study were extrusion polylactide of the Terramac TP-4000 brand, coffee grounds waste with article size limit from 0.5 to 1 mm, dried to moisture content 0,5% and humic substances, which were obtained by extraction of brown coal. The obtained diffusion coefficient values of different liquids are in the range from 0,95 * 10⁻¹⁰ to 6,65 *10⁻¹⁰ m²\sallow us to conclude that the designed brown coal humic substances hybrid modified biodegrada ble materials based on polylactide and coffee waste can be used as a polymer base in terms of their sorption properties for one and multi-use tableware production.

Obtaining hybrid eco-friendly biodegradable structural composites was considered. The aim of this work was to determining the properties of hybrid eco-friendly biodegradable construction composites modified with humic substances. Hybrid eco-friendly construction composites were obtained on the basis of bioplastic polylactides with the addition as a filler of coffee grounds with a polyfractional composition within a particle size of 0.5 mm to 1 mm and a hybrid modifier – humic substances from brown coal. Hybrid ecofriendly construction composites were obtained by extrusion of pre-prepared raw materials in a single-screw laboratory extruder at a temperature of 170–200 °С and an auger rotation speed of 30–100 rpm. Investigated impact strength, breaking stress during bending, melt flow index (MFI) and melting temperature of hybrid ecofriendly biodegradable structural composites modified with humic substances. Optimization studies have been carried out to determine the most effective composition of new ecofriendly structural composites based on bioplastics of polylactides, coffee grounds waste and humic substances of three different types. Researching data together with the data of impact strength, allows us to make assumptions about the possibility of forming a variety of products from structurally composite material, herewith a composition with a coffee content of 50 % by mass. deserves a special attention. The data show an increase the impact strength and the breaking stress during bending a hybrid modification of ecofriendly biodegradable construction composites based on polylactide, coffee grounds waste and humic substances in 2.5 times, with optimal in terms of strength characteristics is the content of coffee grounds at 50 % wt. and 0.5 % by mass humic substances with the highest content of volatile substances and the lowest content of carbon.
