Enhancing heat ef ficiency in organic roof coatings via design for improved durability of thermochromic pigments

Massimo Calovi, Department of Industrial Engineering – UNITN

The research article is an extensive, thorough investigation focused on advancing the thermal efficiency of organic roof-coatings through a dedicated emphasis on fortifying the durability of thermochromic pigments. These specialized pigments possess a unique capability to alter their color in response to temperature fluctuations, which in turn influences the absorption and reflection of solar radiation, thereby impacting the overall thermal regulation within buildings. However, despite their potential to optimize thermal performance, an enduring challenge lies in their susceptibility to degradation over time, hindering their sustained efficacy in maintaining the desired thermal properties essential for these coatings. The primary objective of this ambitious and comprehensive research initiative was to develop innovative methodologies and design strategies that would effectively enhance the durability of thermochromic pigments, ensuring their prolonged functionality and efficacy. This multifaceted endeavor involved a systematic and rigorous exploration of diverse formulations and tailor-made design adaptations meticulously engineered to bolster the resilience of these pigments against an extensive array of prevalent environmental stressors.
