Nanocomposites for Protection Against Thermal Infrared Imaging Detection Systems

The article aims to examine polymeric ceramic-inorganic nanocomposites against thermal infrared imaging detection systems. A literature review was conducted on modern materials and composites that are effective against thermal infrared imaging detection systems. The thermal infrared imaging spectral properties of polymer ceramic-inorganic nanocomposites based on epoxy resin were determined and modified with ceramic-inorganic graphite-ferromagnetic fillers such as potassium titanates, silicon carbide, chromium oxide, and graphite. The scientific novelty of the study established that modification with potassium titanates of composites based on epoxy resin is optimal for enhancing thermal infrared imaging characteristics. The degree of thermal screening for the epoxy resin system with 20% wt. potassium titanates is almost 80%, and the maximum temperature reduction for those systems is from 26.6 to 23.5 ºС. Likewise, the nanocomposites modified with poly potassium titanates were the most successful in lowering the intensity of thermal infrared imaging spectrum bands through analysis of the findings of comparative experiments. The practical significance of the study of all tested nanocomposites is the ability to shield the human body from detection by thermal infrared imaging systems and can be recommended for creating masking screens, sheets, textiles, and constructions.
