“…collisions of the body with the molecules of the medium) or mechanical influences (e.g. contact with the bodies in the medium), the distribution function of the near-surface area particles is altered in accordance with equation (1). This equation, with reference to the microrelief, can be provided in the form:…”

“…Solution of these boundary value problems over a wide range of y will allow one to identify the main relations of the microrelief with the speeds of the elementary processes as well as to describe the response of the function φ (υ, τ ) to the change of y and to develop algorithms for calculating the parameters of elementary processes from the experimental data about the function φ (υ, τ ) at different y. Currently, methods for solving such problems and the models of elementary processes are developed, and experimental data, allowing one to judge the main features of the microrelief and to make a phenomenological model of its formation, is accumulated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. For the quantitative study of the relation between the parameters of microrelief and the elementary processes, it is advisable to start with the simplest system, one in which the initiator molecules are rapidly converted into the nuclei of chain macromolecules, their number in the system reaching the value N 1 = C B V 0 .…”

The model of microrelief formation on the surface of polymers was formulated, describing the connection between the microrelief structural elements' distribution function on the states with the kinetics of macromolecule formation, aggregation and aggregates' integration into the polymer body. Methods for calculating the kinetics of these processes, using experimental data on the microrelief properties, were developed. The developed methods have proven effective in the study of microrelief on films obtained by the evaporation of o−xylene and toluene solutions of polystyrene, as well as polystyrene granules' microrelief. The hierarchical structures were found on the surface of these bodies, from which it was possible to "extract" information about the polymerization and aggregation of the polystyrene macromolecules. The obtained data are summarized in the form of a morphological memory representation of the polymer bodies, consisting in the long-term preservation of nonequilibrium structures available for study without destroying the body, as well as the possibility to use the results of the study to describe the kinetics of these structures' formation.

Surface analysis of nitrogen plasma-treated C60/PS nanocomposite films for antibacterial activity

The influence of N plasma on the antibacterial properties of polystyrene/fullerene (C/PS) nanocomposite films with two concentrations is investigated. A comparison is made between the surface characteristics of the films before and after plasma irradiation for different time intervals. The alterations induced on the surface of the films after treatment are analyzed by contact angle and surface energy measurements, FTIR spectroscopy, and atomic force microscopy. The antibacterial properties, growth, biofilm formation, and adhesion of the nanocomposite films against two multidrug-resistant bacterial strains, Staphylococcus aureus KT337489 and Pseudomonas aeruginosa KT337488, are investigated before and after plasma irradiation. The results indicate that P. aeruginosa is more sensitive to treatment than S. aureus as well as an enhancement of the anti-adhesion of both strains to treated surfaces through exposure.

Effect of the bentonite filler on structure and properties of composites based on hydroxyethyl cellulose, Arabian Journal of Chemistry (2015), doi: http://dx. AbstractGranulometric test and morphological analysis of the bentonite particles were performed using laser diffraction and low-temperature nitrogen adsorption-desorption techniques. Bentonite particles were immobilized into the hydroxyethyl cellulose matrix by mechanical dispersion, and composite films were obtained. The effect of concentration of the filling agent on structure and tensile properties of composites was revealed. Data on the nature of interaction between hydroxyethyl cellulose and bentonite after the modification of polymer was obtained by IR spectroscopy. It was found that the hydroxyethyl cellulose/bentonite composite films showed an antimicrobial effect against E. coli and Staph. aureus bacteria, as well against fungi association.
