Recent advance of phase change materials in paints and coatings: a review
摘要
Phase change materials (PCMs) have capacity to keep a significant quantity of energy in the form of latent heat when undergoing a phase transition, rendering them very suitable for the management of thermal energy storage. These materials exhibit a diverse array of uses in several facets of our everyday existence, encompassing domains such as logistics, construction, electronics, fabrics and more. The integration of PCMs has also been employed in the advancement of paint and coating formulations, resulting in enhanced thermal energy storage capabilities. To date, the utilization of PCMs in composite materials has demonstrated encouraging outcomes across many applications. An intriguing illustration of these substances involves the integration of PCMs inside paint and coating compositions. There have been many reports of paint and coatings being formulated with the inclusion of PCMs to augment their thermal characteristics. The purpose of this review is to provide the latest advancements in the utilization of paints and coatings integrated with PCMs and evaluate their efficacy as thermal energy storage materials. This review also examines the utilization of PCM in various applications such as coating and paint materials in buildings, solar thermal applications, fabrics and other relevant fields. Special attention will be given to the techniques employed in the preparation of composite PCM coatings and paints.
