Thermosensitive Coatings: A Review

The object of the research is thermosensitive materials. Such materials are used in many sectors of the national economy to determine the temperature and measure the temperature fields of the surfaces of objects. Method. The Scopus and Elibrary databases, as well as the Technical Conditions (TC) of some thermosensitive products, were used to search and analyze literature on heat-sensitive materials. Results. The study of thermochromism and the development of thermochromic materials are of great interest due to the ability of these materials to measure the temperature of moving objects and objects located in hard-to-reach places, as well as submicron-sized elements. The article discusses the classification of thermochromic materials, their operating principle, chemical composition and types of temperature indicators, summarizes the experience and prospects for the use of temperature-sensitive materials based on a review of scientific literature. The trend and prospects for the development of temperature-indicating materials is to develop materials with certain established properties for each specific case. Targeted synthesis of temperature-sensitive pigments with the required set of technical characteristics is an urgent task.
