Structural and technological aspects of obtaining composite materials based on polytetrafluoroethylene are considered. It is shown that, due to the manifestation of the inertness of the components in the processes of interfacial interaction with an increase in the degree of filling, a structural paradox appears within the framework of the traditional technological paradigm. This paradox consists i...... hiện toàn bộ
High-Temperature Thermodestruction Analysis of a Polyphenylene-Sulfide-Based Composite by ThermogravimetryPolymer Science, Series D - Tập 16 - Trang 137-141 - 2023
A. V. Kutsenova, E. V. Kalugina, A. V. Samoryadov, V. B. Ivanov
Thermodestruction of a polyphenylene-sulfide-based composite at temperatures up to 800°C was studied by dynamic thermogravimetric analysis. Activation energies Еа were determined using a nonlinear regression analysis within the framework of a kinetic model of the process with two noninterrelated noninteracting stages. Estimates of Еа by this and other methods were compared with the value of Еа dur...... hiện toàn bộ
Development and tests of thermally stable potting and impregnating compoundsPolymer Science, Series D - Tập 5 - Trang 145-149 - 2012
S. N. Gladkikh, E. N. Basharina, O. L. Troitskaya, S. P. Kriulina, N. V. Timoshchenko, I. V. Nikitushkin
The results of investigation of domestic impregnating and potting compounds that can function at temperatures up to 180–200°C developed at JSC Kompozit are presented. It is shown that these materials function at temperatures up to 200°C, as well as under conditions of elevated humidity and temperature cycling.
The Mechanism of the Initial Stage of Synthesis of PolydopaminePolymer Science, Series D - Tập 15 - Trang 30-34 - 2022

Based on the analysis of the regularities of the interaction of dopamine borates and dimethyl silyl ether, two alternative mechanisms of their oxidation for the purpose of obtaining polydopamine as a promising product for the creation of new and efficient adhesive compounds for joining biological tissues are proposed. An explanation of the presence of a threshold concentration of dopamine in the r...... hiện toàn bộ
Thermodynamic model of the effect of nanoadhesion for polymeric nanocompositesPolymer Science, Series D - Tập 1 - Trang 223-225 - 2008
G. V. Kozlov, Z. Kh. Afashagova, G. E. Zaikov
A thermodynamic model of the effect of nanoadhesion in filled polymeric nanocomposites is discussed. The model demonstrates good agreement with experimental data. It is shown that the effect of nanoadhesion has a dimensional origin, i.e., it is a true nanoeffect, which is greatly influenced by the aggregation of filler nanoparticles.
