Case Study

Preparation of Thermochromic Coatings Using 2-(2,4-Dimethylphenylamino)-3-Methyl-6-Diethylaminofluoran

Liu, Shuhan, et al. Case Studies in Thermal Engineering 45 (2023): 102916.

The study investigated how material color affects the optical characteristics of thermochromic coatings that change at 25°C and 33°C to meet architectural surface color requirements. The research team developed twelve distinct thermochromic coatings using 2-(2,4-dimethylphenylamino)-3-methyl-6-diethylaminofluoran (CAS No. 36431-22-8) as the temperature-regulating component. 36431-22-8) as the temperature control agent. Reflectivity measurements revealed substantial increases across all samples during the transition from colored states to colorless states with the most significant reflectivity changes observed in the 1300 nm to 1600 nm and 1900 nm to 2100 nm wavelength bands. Thermochromic coatings showed improved overall reflectivity by 3.17% to 10.68% when tested at 25°C and by 7.22% to 18.23% at 33°C.
A thermochromic coating procedure resulted in a uniform 2 mm layer applied to a 50 mm by 50 mm aluminum foil that measured 0.4 mm thick. The coating darkens when temperatures drop below the transition point but becomes lighter as temperatures increase beyond this point. The thermochromic coatings consisted of polyvinyl chloride (PVC) resin mixed with 6'-(diethylamino)-1',3'-dimethylfluoran dye as well as melamine epoxy polymer and blend solvent including dodecyl gallate as an additive. The coating color adjustment involved the color-forming agent 3,3-bis(2-methyl-1-octyl-1H-indol-3-yl)phthalide while the transition temperature regulation relied on the temperature control agent 2-(2,4-dimethylphenylamino)-3-methyl-6-diethylaminofluoran.
