“…The results showed that the thicker the ink binder layer on the surface of microcapsules, the slower the degradation rate of microcapsules. Kavcic et al [10] applied different printing materials on the printed display and deposited thermochromic ink on the first and second layers. The effects of printing materials, the thickness of the thermochromic ink layer, varnish, temperature and light resistance on the operability of the display were studied.…”

Wood surface decoration and protection has become a topic of public concern. In this paper, a temperature-sensitive and reversible thermochromic waterborne wood coating was prepared by using Chinese fir board as the base material and a waterborne wood coating with the pigment slurry of thermochromic microcapsules as the paint base. The optical properties, mechanical properties and chemical resistance of the waterborne wood coating were tested, and its microstructure was analyzed. The results showed that when the concentration of thermochromic pigment slurry was 30.0%, the thermochromic property of the waterborne wood coating was best. The gloss of the waterborne wood coating with 15.0% pigment slurry of thermochromic microcapsules was high. The concentration of thermochromic pigment slurry had no effect on the adhesion, impact resistance, or chemical resistance of the waterborne wood coating. Based on the above results, the waterborne wood coating on Chinese fir had the best comprehensive performance when the concentration of thermochromic pigment slurry was 15.0%. This work will provide a technical reference for the industrialization of the thermochromic coating film on wood.

Good product packaging is one of the fundamental determinants of the quality of a product. Packaging can protect a product, but it can also be used as an indicator so that consumers know the quality level and shelf life of the packaged products. Along with the development of modern packaging science and technology, it is developing into intelligent packaging that is directly linked to Consumers about the quality and quality of the packaged products without opening the packaging. One of the smart packaging trends that have been developed is thermochromic ink which can be applied in the form of foils or packaging labels. Thermochromic ink is already well developed and applied to textiles and smart windows. Thermochromic ink development on the packaging is used for printing packaging labels and foils placed on the surface of the package. Thermochromic ink changes colour when there is a change in processing and storage temperatures. The ink used is an oil-based synthetic ink with ethanol and water as solvents. The particle size of the thermochromic ink is quite large, and it is quite difficult to obtain a stable colour, so the thermochromic ink must be microencapsulated to protect it from the environment.

“…20 Due to the activity of leuco dye to energy, thermochromic microcapsules are showing a poor heat and light stability. [21][22][23] For example, thermochromic microcapsules and their product lost thermochromism property when thermochromic microcapsules are exposed to sunlight even for a very short time, which greatly limits their outdoor application. 24,25 In recent decades, some reports on the stability of thermochromic materials have been carried out.…”

In this study, a new UV absorptive copolymer was prepared and further applied in thermochromic smart textiles in order to improve its application property. Firstly, UV absorptive copolymer was prepared by solution polymerization using a structural monomer (methyl methacrylate, MMA) and a UV absorptive functional monomer (2‐[3‐(2H‐benzotriazol‐2‐yl)‐4‐hydroxyphenyl] ethyl methacrylate, BHEM), which absorbs UV light effectively and has strong absorption at 230, 305, and 340 nm. And then, a light‐resistant thermochromic fabric with a three‐layer structure was prepared via coating technology. The influencing factors on light‐resistant thermochromic fabrics were systematically investigated by controlling polymerization components and copolymer dosage. The fading rate of the optimized light‐resistant thermochromic fabric after 10 h illumination is only 27.9%, which is 60.9% improvement than thermochromic fabric without a protective copolymer. Light‐resistant thermochromic fabrics with a 36 μm UV absorbing polymer coating shows excellent color fastness, including wash fastness (five grades), wet rubbing fastness (five grades), and light fastness (two grades). Moreover, light‐resistant thermochromic fabrics have good color reversibility and fatigue resistance (100 cycles) properties. And this approach provides a feasible optimization scheme for improving the light resistance of thermochromic textiles.
