Development of a light-responsive fluorinated poly(arylene ether) copolymer containing azobenzene groups in the main polymer chain Ihor M. Tkachenko, Yuriy I. Kurioz, Ruslan M. Kravchuk, Alexander L. Tolstov, Anatoliy V. Glushchenko, et al. Molecular Systems Design and Engineering, 2024 A novel azo-based polymer with high mechanical and thermal stability is obtained. The polymer exhibits stable birefringence changes, enabling the fabrication of diffraction gratings, showing its potential for various optical applications.
Impact of Interface Interactions on a Structure Formation of The Nanostructured Poly(Urethane-Urea) - Poly(Vinyl Chloride) Blends Filled with Modified Nanosilica Tatyana Malysheva, Alexander Tolstov Proceedings of the 2022 IEEE 12th International Conference Nanomaterials Applications and Properties Nap 2022, 2022 Dimethyldichlorosilane (DMCS) modified AM-300 nanosilica has a minor destabilization effect on C=Oδ- ···αHc)+ network and slightly reduces the tensile properties of PUU-I/PVC composites compared to composites filled with unmodified hydrophilic A-300 nanosilica. Introducing modified filler into PUU-2/PVC blend weakens intermolecular interactions at the interface. It sharply reduces the strength of filled polymer composites due to adsorption interactions of residual polar chlorine groups of DMCS modifier and proton donor NH groups of hard segments of the elastomer. At the same time, intracomponent C=Oδ-···αHc)+ interactions are practically unchanged and do not affect phase separation processes and functional characteristics of filled polymer nanocomposite films. It was found the optimal content of the filler for PUU-I/PVC blend reaches 3 wt.% for AM-300 or 1 wt. % for neat nanosilica. However, for PUU-2/PVC a filler content should not overcome 1 wt. %. So, the impact of interface interactions on tensile properties of nanostructured polymer blends depends mainly on the nature of the nanosilica modifier as well as the chemical structure of the poly(urethane-urea) matrix.

Organic/inorganic Dual Network Hydrogels Based on Acrylic Acid and 2-aminoethyl-3-aminopropyltrimetoxysilane: Synthesis and Characterization Olga Slisenko, Iryna Bei, Vira Budzinska, Oleksandr Tolstov Proceedings of the 2020 IEEE 10th International Conference on Nanomaterials Applications and Properties Nap 2020, 2020 A novel dual network (DN) hydrogel composites based on partially neutralized polyacrylic acid (PAANa) and poly-N-(2-aminoethy1)-3-aminopropy1trimethoxysi1ane (PAPTMS) were synthesized by a combination of free radical polymerization of AANa in the presence of N,N’-methylenebis(acrylamide) cross-linker and hydrolysis of silica precursors and catalytically-induced condensation of the resulting hydroxyl groups of APTMS (from 5 to 20 wt.%) to form a network structure. The cross-linking of PAANa was verified by the absence of a C=C double bond by FTIR analysis. TGA of PAANa/PAPTMS hydrogels showed higher thermal stability compared to pure PAA hydrogel as well as the heat-resistance index (TiiRi) for PAANa/PAPTMS composites have greater values than additive ones. The hydrogels’ swelling capacity in distilled water is enhanced by 316% (from 16.81 to 70.06 g/g) at the incorporation of 10 wt% of PAPTMS. The mechanism of diffusion of hydrogels (except PAANa/PAPTMS = 80/20) has non-Fickian or anomalous character. The sorption curve of PAANa/PAPTMS = 80/20 sample has sigmoid character and was interpreted as a result of a combination of first-order kinetics and the overall autocatalytic process with its two rate constants.
Facile preparation of nanocomposite hydrogel sensor for detecting Cu2+ ions contaminant in aqueous media Olga Zinchenko, Valentyna Ezhova, Olga Slisenko, Alexander Tolstov Molecular Crystals and Liquid Crystals, 2020 Novel polymer hydrogel sensor materials were obtained and tested for pH and temperature responsive activity as well as sensitivity to ultralow copper ions content. Copper ion sensitive hybrid composites were prepared via photo-induced copolymerization of a mixture of acrylics and pre-synthesized methacrylate functionalized ZnO nanoparticles. Sensor activity of the composites is caused by extinguishing fluorescence of nano ZnO under impact of Cu2+ ions contaminant. It was observed a substantial increasing fluorescence intensity while Cu2+ ions content falls down from 10−1 to 10−6 mol/L. The acrylic matrix demonstrates pH and temperature responsive behavior as well.
