Khalifa University, as recorded in Wikipedia, specializes in the fields of thermochromic materials, which are utilized in the industrial sector as temperature indicators to identify the difference in heat, response in chemicals, and distribution of temperature of heat exchangers. These materials are usually organic leuco-dye mixtures consisting of a combination of color, developer, and a liquid dissolving substance.

At room temperature, the thermochromic paint displays a certain color, but at a specific temperature, the color vanishes. For example, applying black thermochromic paint on a white surface produces a dark surface, but at 27°C, it transforms into a white surface. If applied to an orange surface, it shifts from dark to orange at the same temperature. The pigment's color reverts when the temperature drops.

Thermochromic materials vary their optical attributes when exposed to a sudden change in temperature. For instance, VO₂ is a "smart" window that transitions from a transmissive to an infrared reflective state, depending on the temperature. The wavelength of energizing for temperature can range from 350 to 1800nm, relying on the material's optical constants. The defunctness constant determines how the wavelength is dispersed at the interface, and the index of reflection of the material determines the magnitude of this dispersion. This constant varies according to the material's makeup, sizing, configuration, and dielectric or insulator environment.

It was discovered that the index of refraction of thermochromic pigments improved by 13% to 22% in the 350 to 1800nm armpit wavelength. The conversion temperature, which refers to the temperature by which the phase variation between the transmissive and reflective state takes place, affected the index of refraction changes.

Kim et al described a thermochromic supper window with exceptional mechanical tractability by using carbon copy as a platform for VO₂ to create conciliatory films that could change transmission of light with the environment temperature. The unique feature of VO₂ is that it emits in the close-infrared domain, acting as a semiconductor, and reflects in other domains above the temperature transition. This behaviour stems from the transition phase from a monochromatic tetragon.

Various types of thermochromic materials are available, and the figure below displays the scopes of Fourier Transform Infrared and TC-PCMs. The thermochromic compound's attribute apex at 1579 cm⁻¹ indicates that it is present in all TC-PCMs lines. Additionally, various other peaks indicate other group vibrations.

The transition temperature of TC-PCMs reduces slightly as the doping amounts increase. Conversely, heat content values increase to varying degrees. This effect can be attributed to the greater inclusion of the thermochromic universal, which promotes the creation of the rotator phase and crystalline structure of 1-HD. As a result, a sufficient increase in ODB-2 and NPA had little impact on the phase transition temperature but did increase the heat content values of TC-PCMs.

The crystallizing features were attributed to X-ray diffraction. These are exhibited in the figure, showing that distinct apexes of diffraction of 1-HD were discovered at angles of 2θ = 20.6⁰, 21.4⁰, 21.8⁰, 22.1⁰, 24.2⁰, and 24.7⁰, similar to the TC-PCMs. In graphs c-e, the apexes at 21.4⁰ and 21.4⁰ are weakened - likely due to the doping of dyes. In graph b, the diffraction apex is almost unchanged, indicating that doping near TC-PCM 180 does not have a significant impact on the crystallinity of 1-HD.

To investigate the management of temperature systems of thermochromic materials, the thermal transition was experimented with portraits or graphic-thermal transition graph of PC-PCMs and CB₁₈₀. Under the light of the sun beam (0.09W/cm²), the heat balance temperature belonging to TC-PCMs was evidently lower than that of CB₁₀₀․ This outcome is due to the geomorphological transformation belonging to the compound of thermochromic at the time the temperature was of higher magnitude exceeding the temperature of the conversion phase belonging to 1-HD․ In addition, the heat balance temperature of TC-PCM₁₈₀ remains at 56⁰C in contrast to that of CB₁₀₀ that has a temperature more than 64⁰C. Other curves/graph of TC-PCMs indicate that they obtain lower thermal balance temperatures at higher frequencies of simulation power and source of light of simulative, which is about 0.14Wcm². Hence, as the smallest compound of the TC proportion which is a fraction of mass and compound of TC is about 1.59%, TC-pcm₁₈₀ can achieve a lower balance temperature below low or high enlightening power. This outcome shows that TC-PCM₁₈₀ exhibits good temperature-management character for image-heat transition.

To explore more about the management of temperature dimensions of various PCMs together with the compound of thermochromic, we chose one tetradecanol PCM at an optimum proportion of 1:2:180 of ODB-2 to BPA-1. Under the sun's ray, the outcome as exhibited in the graphs of 1-tetradecanol indicates various heat temperatures of 17.5⁰C and 43.4⁰C, showing that the temperature of the system could be managed by irradiation.

The manufacturing process involved different proportions of TC-PCMs, concocting 1-HD, BPA, and ODB-2 at weight proportions of 1:4:30, 1:4:60, 1:3:40, and 1:4:150. 1-HD was melted at 79⁰C for one hour through oil. Afterwards, BPA and ODB-2 were thawed in 1-HD with changing percentages in 179⁰C thermochromic oil liquid unit for a duration of two minutes. CB₁₈₀ was achieved by substituting ODB-2 using CB, which is an abbreviation for black carbon in the element of TC-PCM₁₈₀. 1-tetradecanol substituted ONE HEXADECANOL at the proportion of 1:3:178 systems, which achieved individuality.

In conclusion, TC-PCMs exhibit good temperature management properties for image-heat transition, making them suitable in various applications.

In the image-heat transition dimension experiment, sun radiation and assumed light were used. A CHF-XM35-500W lamp of xenon was used in a collimate light reservoir system to mimic sun radiation. Prototype Ligh were used as portraits reserves. The lamp of xenon produced light with consistent wavelengths ranging from 200nm to 2000nm, with similar energy dispersion as the sun. Close-infrared light between 700nm and 1100 nm, which increases energy dispersions significantly, was filtered out by an IR-CUT filter.

The intensity of light from sunrays was approximately 0.09W/cm², and assumed light with a stable amount of sunlight radiations was selected to explore photo-heat transition functioning through high-intensity light. The power was measured using a visual power meter, and temperature values were recorded every four seconds using a numerical check thermometer.

Thermochromic materials change color depending on the temperature. They are used in various products, including toys, clothing, thermometers, battery testers, fraud prevention devices, and temperature indicators for food. When materials admit and reflect certain light wavelengths, they appear colored. Thermochromic materials change their chemical and physical properties when they absorb and emit various wavelengths of light due to heat, resulting in a change in appearance. Leuco dyes are used in various thermochromic products and can be integrated into different materials, including inks, plastics, and synthetics. Some places use leuco dyes to print hidden symbols on tickets that become visible when scratched by a warm hand.

Liquid crystallization is costly and difficult to apply, but it can be used to change color at specific temperatures, making it suitable for products like forehead thermometers and mood rings. However, there is no scientific evidence to support the idea that mood rings are accurate indicators of a person's mood. As designers find new applications for smart materials, the future looks very promising.

Phosphorescent pigment is available in powder form and can be used to create a glow-in-the-dark effect for a longer duration than zinc sulphate-based phosphorescent materials. The pigment can be mixed with an acrylic paint white in color and diluted with water solvent, allowing it to dry expeditiously. As the acrylic paint solidifies, it effectively interlocks the pigment into a water-repellent film. The effectiveness of the paint depends on the ratio of acrylic and the thickness of the film used.

The smart pigment's acrylic medium is suitable for application to fabrics, plastic, and paper. The paint can be mixed with any acrylic pigment, and the creative possibilities are endless when different colors are combined. For example, when blue paint is mixed with yellow acrylic paint, the resulting color is green. However, at a temperature of 28⁰C, the blue color disappears, and the green color changes to yellow.

Overall, these smart materials have numerous applications in various fields and industries.

The use of phosphorescent pigment is crucial in creating an experiment strip with plastic or plain paper. By mixing various amounts of pigment with acrylic base or white acrylic paint and solvent water, the result is a fluid nature. Once the experiment strip is created, it should be allowed to dry in a warm location.

After it has thoroughly dried, the strip needs to be exposed to sunlight or bright light, such as a flashlight, for 30 minutes. In a dark area, the strip should emit a glow that lasts for up to eight hours. This pigment is especially reactive to UV rays, making it perfect for showing glow-in-the-dark products in the retail industry.

During nighttime, the phosphorescent pigment can provide a clear visible light in experimental conditions of complete darkness. It can even act as a temporary photographic plate, making it recreationally useful. But more importantly, it has various applications, such as traffic signs, path construction, printing inks, and emergency augury and management equipment.

Both thermochromic and phosphorescent pigments are made with acrylic, making it possible to adjust the viscosity of the base using water as a solvent. For instance, a thinner mixture is ideal for brush-based painting, while a denser mixture is perfect for screen publishing.

To use thermochromic pigment, simply dilute a small amount of acrylic base with water and apply it using a pigment brush. Once the surface dries in a warm environment, the color-changing effect will be visible even before the surface is completely dry.

As a precaution, paints and pigments should be kept in a dry and cool environment and away from moisture. Use a minimum amount of pigment to get the desired effect, and dilute the acrylic medium with solvent water for faster application and drying.
