Formation of diode-like composite membranes 
by plasma polymerization

L. I. Kravets, A. B. Gilman, V. Satulu, B. Mitu, G. Dinescu


This paper outlines the method of the polymer ‘diode-like’ composite membranes preparation that possess asymmetry of conductivity in electrolyte solutions (rectification effect) which manifests itself at various orientations of membranes in an electric field. To produce membranes with ‘diode-like’ properties, thin polymer films formed by plasma polymerization of organic precursors were deposited on one side of track-etched membranes from poly(ethylene terephthalate) and polypropylene used as the porous substrate. It is established that principal causes of achieving asymmetric conductivity are the change in the pore geometry due to the essential reduction of their diameter in the layer of the deposited polymer, and the existence in the pores of an interface between the initial membrane and deposited polymer layer. It is shown that in the presence of a polymer layer with hydrophobic nature in composite membranes for description their electrochemical properties, in addition to consideration the electrostatic interaction between the electrolyte ions and the charge existing on the pore walls, the phenomenon of slipping of the electrolyte solution along the hydrophobic surface should also be taken into account. The detected effects indicate a possible way of the composite membranes creating with asymmetry of conductivity that can be used to develop various feedback systems, chemical and biochemical sensors.

 

Keywords: track-etched membranes, polymer ‘diode-like’ composite membranes, plasma polymerization, asymmetry of conductivity, rectification effect.

The research explores the influence of severe plastic deformation on the physical and mechanical properties of ultrafine-grained 1560 Al – 7 Mg-based alloy, which was processed by the methods of equal-channel angular pressing. A non-destructive testing technique based on three-dimensional X-ray tomography and ultrasonic inspection was suggested for detecting internal structural defects and monitoring damage formation in the alloy structure after processing. The microstructure of the studied material was analyzed to determine the shape and size distributions of grains in the volume. The grain size distribution in the as-received alloy varied in the range from 4 to 400 µm, and the average grain size was equal to about 50 µm. After four pressing passes, a more uniform structure was obtained within the bulk with the average grain size about 3 μm. Microhardness tests and uniaxial tensile tests under quasi-static loading were conducted to investigate the mechanical properties of the alloy in the as-received condition and after severe plastic deformation. The average microhardness of the material increased after treatment from 1000 to 1600 MPa in the entire volume of blocks. According to tensile test data, the yield strength and ultimate tensile strength increased after four stages of treatment from 150 to 270 MPa and 320 to 460 MPa, respectively. All experimental data prove that severe plastic deformation in optimal treatment conditions enhances the strength characteristics of structural 1560 alloy.

 

Keywords: aluminum alloy, grain structure, mechanical properties, severe plastic deformation.

The procedure for preliminary activation of the zeolite surface by NaOH solution allows to optimize the process of immobilization of hyperbranched polyester polycarbamate on the zeolite surface. The increase in the sorption capacity of a new chemo-modified sorbent with respect to Cu (II) ions in model solutions has been proved. Obtained data will allow to develop the sorption extraction technology of rare earth metals ions from objects of ecological control.

V. E. Silantiev, P. Yu. Lizunova, K. O. Shornikov


In article we present the results of research concerning influence of additive on the basis of synthetic wollastonite obtained by autoclave method from boric acid production waste (borogypsum) on the functional properties of concrete (strength, frost-resistance and water absorption). The phase composition and morphology of the obtained material were studied. It was found that the phase composition of the obtained material after autoclaving and subsequent annealing at 1200 °C is characterized by the presence of crystalline phases of pseudowollastonite, wollastonite and calcium sulfate. It was shown that the 3.5 wt. % wollastonite-based addition leads to increase the strength of fine-grained concrete (compressive strength to 26 % and bending strength to 46 %) and decrease the water absorption of the samples by mass and volume almost twofold. It was found that the 3 – 3,5 wt. % wollastonite-based addition leads to increase the number of alternating freezing and thawing cycles of concrete. It indicates the increasing of its frostresistance.


Key words: wollastonite, borogypsum, concrete, strength, frost-resistance and water absorption.

Carbon nanotubes for improving the antifriction
properties of motor oils

I. V. Zaporotskova, I. V. Arkharova


A method is proposed for improving the antifriction characteristics of motor oils by introducing carbon nanotubes into its composition. The technique, conditions and results of the experiment with the discussion are considered in the article. The purpose of this work was to develop a method for increasing the efficiency of the oil composition by introducing an additive containing multilayer carbon nanotubes (MWNTs) in various concentrations (0.01, 0.1, and 0.5 wt.%) into the motor oil and studying the effect of carbon nanotubes, introduced as an additive, on the index of antifriction properties of the resulting lubricating compositions — coefficient of friction. As a lubricating medium, various motor oils were selected: on a mineral basis — Lukoil Standard 10W-40 SF/CC; On a partially synthetic basis — Lukoil Lux 5w-40 SL/CF; On a synthetic basis — Lukoil Lux 5w-40 SN/CF. Tests of oils were carried out on a universal friction machine MTU-01 (TU 4271-001-29034600-2004), which is designed for testing friction and wear of metallic and non-metallic materials under the conditions of various lubricating media. The obtained experimental results showed that the introduction of multi-walled carbon nanotubes at low concentrations into engine oils has a positive effect on their antifriction characteristics, which in turn will reduce the energy costs of the idle drive of the machine elements by reducing the coefficient of friction.


Keywords: Carbon nanotubes, lubricant additives, antifriction properties, friction coefficient, friction test machine.

The new generation porous metal-ceramic membranes have been developed by the SHS method in vacuum from a mixture of a large nickel powder (average particle size is 100 μm) and fine powders of cobalt oxide Co3O4 (average particle size is 10-15 nm) and aluminum (average particle size is 5 – 10 μm). During the synthesis, the membrane frame is formed from large particle fractions with open pores of 2,6 – 5,1 μm in size, which leads to an increase in membrane permeability and a large expenditure of the substrate. As a result, porous metal-ceramic catalytically active membranes containing nickel and cobalt nanoparticles with a size of 10 – 20 nm in surface pore layers have been obtained. It have found that the complete conversion of dimethyl ether (DME) is achieved at a temperature of 450 °C to obtain synthesis gas and ultrapure hydrogen.

The introduction of nanosized natural minerals of Azerbaijan — vesuviane and clinoptilolite into the composition of such understudied polyolefins as statistical (random) ethylene-propylene copolymer and ethylene-propylene block copolymer for the first time is allowed to discover new possibilities for obtaining bifunctional nano-composites based on them. Bifunctionality is expressed not only in the possibility of obtaining highly filled nanocomposites with improved strength properties, but also in a significant increase in the melt flow index, which improves their processability. Scientific based arguments explaining the reasons for improving the flowability of the melt of nanocomposites in comparison with the initial polymer matrix is shown. In this connection, the influence of technological parameters of injection molding and concentration of mineral filler on strength characteristics and volumetric shrinkage of nanocomposites is described.
