Improving the thermal efficiency of roof-coatings
A recent work proposes the improvement of the thermal efficiency of organic roof-coatings through design aimed at increasing the durability of thermochromic pigments.
A new work aims to improve the thermal efficiency of roof-coatings, by appropriate design of the samples. The pigments that provide thermochromic features to organic coatings, in fact, are susceptible to rapid physical-chemical degradation when exposed to atmospheric agents. Consequently, the study evaluated the effect of an additional top-layer with the task of increasing the durability and thermochromic efficiency of the pigments.
Long-term thermochromic efficiency
As the researchers point out, theor work demonstrates that the durability of the pigment, and consequently the thermochromic features of the coating, can be improved by applying an additional protective layer to the sample. Thus, this type of sample can be employed as roof-coating, with high long-term thermochromic efficiency.
The study has been published in Progress in Organic Coatings, Volume 185, December 2023.
