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
A. V. Varankin, A. A. Artyukhov, M. I. Shtil’man, Ya. O. Mezhuev
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
A Study of the Properties of Polymer Coatings Based on an Organosilicon MaterialPolymer Science, Series D - Tập 15 - Trang 374-378 - 2022
V. V. Kartashova, N. I. Baurova
Results are given of comprehensive experimental studies of coatings based on a graphite-filled organosilicon sealer. The antiadhesive properties of the studied polymer coating upon its coming into contact with working media were estimated. The friction coefficients and wear resistance of the coatings were determined, and their values were found to be better in the graphite-filled polymer coatings,...... hiện toàn bộ
