Registration Date 07-06-2023 Organization Institute of Organic Chemistry NAS of Ukraine popup.description1 The project is aimed at significantly expanding the possibilities of creating and using polymer composites with extreme properties by developing a universal platform for binders and a new approach to aromatic nitriles as building blocks for heat-resistant polymers that combine high working temperature, high mechanical strength, and resistance to thermo-oxidative destruction. Currently, Ukrainian researchers and material developers do not have reliable access to binders that provide the creation of polymer composites with a long-term heat resistance limit of 350-450 °C for the aerospace industry, energy, and communication systems. The research plan involves the development of protocols for the synthesis of aromatic tetranitriles, adapted for potential semi-industrial scaling. An economically feasible approach to the synthesis of oligomeric systems, doped with Si-B-P nanoclusters, will be developed. Also, a previously unknown mechanism of partial deactivation of reactive chains of thermo-oxidative destruction through up-conversion energy dissipation of migrating radicals will be studied. Based on the synthesized binders, samples of heat-resistant composites with fibrous and dispersed fillers will be obtained and their characteristics studied popup.nrat_date 2024-12-09 Close
