Polyethylene films containing 0.1-1.5% of mass of n-SiΠ‘ and n-Si nanoparticles have been produced by the extrusion method. Using the spectral analysis method, it was found that the obtained films absorb UV radiation in the range 200-400 nm, which is harmful to organic substance. The average particle sizes and the quality of their dispersion in the films were determined by X-ray diffraction analysis. Using differential scanning calorimetry and physical and mechanical tests, it was found that nanoparticles did not affect the formation of the internal structure of the matrix polyethylene. The degree of crystallinity, the melting point and crystallization remain unchanged. The properties of the film surface, studied by the tribological, triboelectric methods and the determination of the wetting angle, remain constant and do not differ from the properties of PE films with nanoparticle content 0.1-1%. At 1.5% n-SiC content, a change in the surface microrelief is diagnosed, leading to a slight increase in the friction coefficient of the films. The polyethylene films filled with n-SiΠ‘ and n-Si obtained in this work are recommended for use as UV protective coatings for various purposes.Π Π½Π°ΡΡΠΎΡΡΠ΅ΠΉ Π½Π°ΡΡΠ½ΠΎ-ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°ΡΠ΅Π»ΡΡΠΊΠΎΠΉ ΡΠ°Π±ΠΎΡΠ΅ ΡΠΊΡΡΡΡΠ·ΠΈΠΎΠ½Π½ΡΠΌ ΡΠΏΠΎΡΠΎΠ±ΠΎΠΌ Π±ΡΠ»ΠΈ ΠΏΠΎΠ»ΡΡΠ΅Π½Ρ ΠΏΠΎΠ»ΠΈΡΡΠΈΠ»Π΅Π½ΠΎΠ²ΡΠ΅ ΠΏΠ»Π΅Π½ΠΊΠΈ, ΡΠΎΠ΄Π΅ΡΠΆΠ°ΡΠΈΠ΅ 0,1-1,5% (ΠΌΠ°Ρ.)

Film Materials Based on Polyethylene with Silicon Nanoparticles and Silicon Carbide
Abstract: In this research and development, the extrusion method was used to obtain polyethylene films containing 0.1β1.5 wt % n-SiC and n-Si nanoparticles obtained by the plasma chemical method. Using the spectral analysis method, it was found that the films obtained absorb UV radiation in the range of 200β400 nm, which is harmful to organic matter. The method of X-ray structural analysis was used to determine the average size of particles and the quality of their dispersion in the films. Differential scanning calorimetry and physicomechanical tests have shown that nanoparticles do not affect the formation of the internal structure of the polyethylene (PE) matrix. The degree of crystallinity, melting point, and crystallization point remain unchanged. The properties of the surface of the films, studied by tribological and triboelectric methods and determination of the contact angle, remain constant and do not differ from the properties of PE films with a nanoparticle content from 0.1 to 1%. At 1.5% nSiC content, a change in the surface microrelief is diagnosed, leading to a small increase in the film friction coefficient. The polyethylene films filled with n-SiC and n-Si obtained in this work are recommended for use as UV protective coatings for various purposes. Β© 2021, Pleiades Publishing, Ltd
Modification of nanocrystalline silicon by polymers for biomedical applications [ΠΠΠΠΠ€ΠΠΠΠ¦ΠΠ― ΠΠΠΠΠΠ ΠΠ‘Π’ΠΠΠΠΠ§ΠΠ‘ΠΠΠΠ ΠΠ ΠΠΠΠΠ― ΠΠΠΠΠΠΠ ΠΠΠ ΠΠΠ― ΠΠΠΠΠΠΠΠ¦ΠΠΠ‘ΠΠΠ₯ ΠΠ ΠΠΠΠΠΠΠΠ]
In this paper, it is proposed to use polymer-modified composite materials based on nano-crystalline silicon (nc-Si) as an alternative to organic fluorescent quantum dots traditionally used in medicine. A distinctive feature of nc-Si is a high absorption coefficient in the near UV and blue-violet range and the ability to transmit light in the visible region of the spectrum. The main ad-vantage of silicon-based nanoparticles for in vivo use is their biodegradability and the absence of toxic properties. For hydrophilization of silicon nanoparticles, their surface was modified by am-phiphilic biocompatible polymers: polyvinylpyrrolidone, a copolymer of maleic anhydride and 1-octadecene, cremophore, which is a polyoxyethylene derivative of hydrogenated castor oil. Silicon nanoparticles (nc-Si) with an average diameter of 4.5 nm, synthesized by annealing of SiO at 1150 Β°C, and functionalized with 1-octadecene photoluminescent in the red-infrared spectral region were used. The presence of the polymer shell on the surface of the nanoparticles was confirmed by FTIR spectroscopy. The sedimentation and aggregative stability of the particles in water were analyzed. It is shown that after the nc-Si polymer modification, the photoluminescent properties of nanopar-ticles are retained although the photoluminesce maxima were shifted to the blue region. Colori-metric MTT-assay of the cytotoxicity of the nanoparticles modified with polymers to monoclonal cells of human erythroleukemia K562 showed no toxicity for cells in culture at a particle concen-tration of up to 50 ΞΌg/ml. Subcellular localization of silicon nanoparticles into the human cervical carcinoma cell line HeLa was shown by means of fluorescence microscopy. The obtained polymer-modified nc-Si particles can be recommended for the purposes of bioimaging in in vitro and in vivo applications. Β© 2019, Ivanovo State University of Chemistry and Technology
