The paper presents data on obtaining of an intermetallic nickel matrix, reinforced with refractory compounds particles of different composition and concentration. The Ni3Al – Cr – W –Mo – Ti – Hf alloy (VKNA-1B) and its analogue with an increased content of W (VKNA-1B (W)) were used as the base of composite materials. For the reinforcement of the intermetallic matrix, Al2O3, Al2O3∙Y2O3 and Al2O3∙Y2O3∙HfO2 nanoscale oxides were chosen with a concentration of reinforcing component 2 and 5 vol. %. The samples were compacted by spark plasma sintering (SPS). The microstructure of MCM samples was performed by scanning electron microscopy. Toughness and flexural strength testing of MCM samples at room temperature were studied. According to the testing data, the dependence of the influence of reinforcing filler concentration and its composition on the physicomechanical properties of a high-temperature cermet material based on an intermetallic matrix dispersed-hardened by particles of refractory metals is established. The obtained data demonsrated the optimal ratio of bending strength and impact toughness at room temperature, which is achieved in a cermet composite material using the intermetallic composition based on VKNA-1B(W) alloy and Al2O3∙Y2O3∙HfO2 oxide as a strengthening matrix phases with a volume content 2 %.
Keywords: nickel intermetallide, nickel aluminide, composite pellets, powder, structure, composition, reinforcing filler, oxides, dispersion strengthening, mechanical activation.

Physical-mechanical characteristics of composite based
on polyimide matrix filled with tungsten oxide
V. I. Pavlenko, G. G. Bondarenko, N. I. Cherkashina
The article presents the possibility of obtaining polymer composite materials based on thermoplastic polyimide and tungsten oxide (WO3), modified with a hydrophobic silicone fluid. Presents data on surface microscopy, Vickers microhardness, density and thermal stability of composites with different tungsten oxide contents. As a result of modifying tungsten oxide, its surface becomes hydrophobic, the contact angle increases from 31 to 101 °. The microstructure of the surface of composites has a fine-grained structure without microcracks and chips. The lowest density material has no filler. With increasing filler content, the density increases. When the content of the filler is 80 wt% density is 4.35 g/cm3. The optimum content of tungsten oxide filler is 60 wt. % by weight, as measured by the surface microhardness. The work shows that the introduction of the proposed filler significantly increases the heat resistance of polyimide. Pure polyimide is stable up to 425 °С, and at a temperature of 680 °С its full thermal decomposition takes place. With increasing content of modified tungsten oxide in the composite, the rate of mass loss decreases. In the composite containing 60 wt.% filler at 680 °C. Mass loss is 38 %.
Keywords: polyimide matrix, modification, hydrophobization, surface microstructure, microhardness, thermal stability.

Release kinetics of doxycycline encapsulated
in polylactoglycolide
scaffolds using supercritical carbon dioxide
E. N. Antonov, L. I. Krotova, S. A. Minaeva, V. K. Popov
Supercritical fluid encapsulation of doxycycline into aliphatic polyesters was used to fabricate bioresorbable antibacterial polylactoglycolide scaffolds. Doxycycline concentration distribution on a surface and in a bulk of polymer structures have been analyzed using high (≈ 1 μm) spatial resolution Raman spectroscopy. The release kinetics of doxycycline from these scaffolds into saline solution was studied. It is shown that, with the exception of the first 3 hours, when about 15% of its total amount goes into the solution, the release of doxycycline occurs almost linearly. During the first day, the total yield of the antibiotic was about 22 %. For 15 days (maximum observation time), the total amount of doxycycline released from polylactoglycolide scaffolds was about 70 %. Thus, bioresorbable polymer scaffolds fabricated with supercritical carbon dioxide can be used for local sustained antibiotics release, as well as for biologically active scaffolds for tissue-engineering.
Keywords: Sustained drug release, polylactoglycolide scaffolds, supercritical carbon dioxide, doxycycline encapsulation, release kinetics.

Low-temperature solution-based method for the production of hybrid organic-inorganic nanocomposites films based on nanoscale cellulose and magnetic iron oxide nanoparticles (CNC/Fe3O4) was developed. The obtained nanomaterials were investigated by scanning electron microscopy (SEM), dynamic light scattering (DLS), energy dispersive spectroscopy (EDS) analysis and X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA) and FT-IR spectroscopy. The formation of CNC/Fe3O4 nanocomposite was confirmed by XRD analysis. According to SEM images, Fe3O4 nanoparticles are evenly distributed on the surface of nanocellulose. The obtained nanocomposites exhibit photocatalytic properties under visible light and UV-irradiation. Thus, the developed biocompatible and environmentally friendly hybrid nanomaterials have a great prospect of the practical application in the field of biomedicine and photocatalysis.

Ye. I. Kulish, V. P. Zakharov
The article is devoted to the development of a polymer composite material with high physicо-mechanical performance indicators and weather resistance based on secondary polypropylene and triple ethylene-propylene-diene rubber. The use of secondary polypropylene in polymer composites in passing solves the problem of recycling secondary polymeric raw materials. To achieve this goal, we studied the effect of simultaneous action of the two most aggressive environmental factors (UV radiation and air oxygen), as well as natural aging on the physico-mechanical characteristics of composite materials based on secondary polypropylene and triple ethylene-propylene-diene rubber with different mass relationship. It was found that the introduction of triple ethylene-propylene-diene rubber in an amount up to 40% by weight. in polymer compositions based on secondary polypropylene, on the one hand, slightly reduces the depth of their photo-oxidative transformations as compared to unfilled polypropylene, and on the other hand, allows to keep practically unchanged, and in some cases even slightly improve the deformation-strength characteristics (modulus of elasticity, rupture stress and burst elongation) of polypropylene materials with the prolonged exposure to UV radiation in air and in natural aging.
Keywords: secondary polypropylene, utilization, triple ethylene-propylene-diene rubber, natural aging, modulus of elasticity, tensile stress, tensile elongation.

Investigation of the effect of VK carbonyl iron powder
on the compressibility and strength characteristics
of sintered atomized iron powder
V. Yu. Lopatin, Zh. V. Eremeeva, N. D. Nguyen
The paper presents the results of studies to determine the effect of carbonyl iron powder VK on compactibility, sintering and mechanical properties of samples from powdered iron powder PZHRV 2.200.26, which is manufactured on an industrial scale in the Russian Federation. It is shown that the relative density of powder formings from the atomized iron powder PZHRV 2.200.26 can be increased by adding particles of carbonyl iron powder VK, which are mainly located in the pores between the particles of the sprayed powder. The addition of solid lubricants to the mixture of powders PZHRV 2.200.26 and VK does not lead to a further increase in the relative density of compacts (more than 90 %). It was established that the addition of VK carbonyl iron powder to the atomized powder PZHRV 2.200.26 in an amount of 15 – 20 % by weight reduces the bending strength of green compacts due to the difficulty of plastic deformation of the atomized particles into the pores, but increases the bending strength of the material after sintering due to the formation more developed contacts.
Keywords: atomized iron powder, carbonyl iron powder, powder mixture, granulometric composition, compactibility, bending strength.

Physic-mechanical and thermo-mechanical
properties of polymers and composites
as influenced upon by the nature
of epoxy-isocyanate binders when polymerized

The cyclopolymerization reaction between bi- and tri-functional epoxy resins and variously structured di- and polyisocyanates (4,4-diphenylmethane diisocyanate, isophorone diisocyanate, polyisocyanate) was studied by the differential scanning calorimetry method. The polymerization reaction proceeds at high temperatures. There was found out a difference in reactivity of epoxy resins and diisocyanates. Aliphatic epoxy resins and an n-aminobenzoic acid-based nitrogen-containing resin appeared to be most active. Cycloaliphatic isophorone diisocyanate was less active when reacted with the resins, as compared with aromatic diisocyanates. To accelerate the reaction between epoxy resins and diisocyanates, complex compounds of zinc chloride with tributylphosphate and imidazole as new catalysts were offered and studied. The use of these catalysts enabled to by 40 – 100 °C lower the temperature of the reaction onset. Chemical interaction between aromatic and cycloaliphatic diisocyanates was studied by the FTIR spectroscopy method. The reaction afforded polyoxazolidones and polyisocyanurates as the main products, the content of which in the polymer was dependent on conditions of the process and on the nature of a catalyst and a diisocyanate. The obtained polymers and composites (organoplastics) are featured by a high glass transition temperature (187 – 202 °C), are heat-resistant and thermally stable in a wide range of temperatures.
Keywords: epoxy resins, diisocyanates, oxozolidones, isocyanurates, catalysts, heat-resistance.
