The market for thermochromic materials is showing substantial growth with a compound annual growth rate (CAGR) of 7.78% during the forecast period (2024-2029).
Thermochromic materials are substances that have the property of changing color when there is a temperature change. The material can be inorganic or polymer based such as iron oxide (Fe3O4), iron silicide (FeSi2), niobium dioxide (NbO2), etc. The color-changing properties of the material could have broad applications in the fields of sensors, displays, anti-counterfeiting, biomedicine, and many others. The major driving factor is the growing usage of these materials in the labels, coating, paint, ink, and pigments for exhibiting the property of thermochromism.
Thermochromic materials are segmented based on the material type into liquid-crystal, leuco dyes, pigments, and other materials. These materials show different properties for different applications. Thermochromic liquid crystals, used for acute thermal sensitivity, detect very small temperature changes. It undergoes a reversible thermally induced color change. They are calibrated to display green at a rated temperature. Another common type used is Leuco dye. They exhibit color change over a temperature of approximately 5ºF (3ºC). It undergoes a reversible color change. They are available in different forms, such as slurry, powder, paint, water-based ink, epoxy, or masterbatch. Leuco dyes can be designed to respond to broad temperature changes in different colors.
The construction and building industry is growing across regions due to the demand for expanding urbanization. Developing economies need more buildings and houses, thus increasing the demand for the raw materials used in the industry. According to the United Nations, around 57% of the world's population in 2022 resided in the cities, which is likely to grow in upcoming years. The demand for innovative materials, such as thermochromic materials, has increased in the sector, owing to their use in roofs for energy saving.
Certain researches are ongoing with their daily life application. The smart roof and windows would use the thermochromic materials properties to draw the right amount of light from the sunlight and then reflect the rest. It could keep the house warm in cold countries and save electricity and carbon emissions. Further, the materials would come with the property that they are not blocking the photovoltaic cells for charging. Thermochromic materials can be economical, energy-saving, and environmentally friendly for application in houses and buildings.
Thermochromic materials have been a growing application in multiple fields, such as camouflaging in the military application; thermochromic dyes are used, which absorb the incident radiant energy and get heated to become colorless. Such dyes are useful applications in the fashion industry, too, where clothes are offered with color-changing properties. Thermochromic dyes are been used in electrical devices where the color change is used for getting the overload warnings.
Moreover, one of the larger applications of the thermochromic technology has been done by the automobile industry. BMW launched a unique color-changing car that uses many advanced technologies. The car has several sensors and cameras for detecting surrounding temperature and lighting conditions. These sensors and equipment then connect with the car computers, which change the car color accordingly. These changes take place in real time, giving an exquisite look. The car has specialized paint for changing color when exposed to different temperatures. These paints are made up of tiny pigments that are temperature-sensitive and suspended in a clear liquid coating.
With the growing demand for the food and beverages, cosmetics industry, and other industries the need for advanced packaging has also increased due to the competitive nature of marketing in the industries. The companies are looking for new and innovative packaging solutions for product differentiation. One such offering is thermochromic inks by the ProAmpac, which features color-changing ink technology that changes color upon reaching a critical temperature threshold. As the temperature decreases, the ink reverts to its original color. This capability allows for versatile applications, and full-color transformations can be achievable.
Further, in July 2022, Molson Coors launched limited-edition packs featuring labels that change color according to the drink's temperature. The company is using thermochromic ink, which can turn the mountain peaks on Coors bottles and cans blue when the beer is cold enough to drink. The company pioneered this type of technology in its beer products.
North America would play a crucial role in developing the thermochromic materials market. The thermochromic materials are innovative in their application and development; thus, the countries in North America would play a crucial role in their execution. Agriculture, food, and related industries contributed roughly $1.530 trillion to U.S. gross domestic product (GDP) in 2023, a major contributor to the packaging industry. Further, the usage of thermochromic materials in buildings for roofs and windows has been growing, which is useful for energy efficiency and carbon saving. Further, many automobile companies are using thermochromic materials for the color-changing properties of the car, giving it a luxury look and expanding the market.
