Functional Coatings for Built Environments Based on Nanotechnology

Coatings provide underlying item surfaces or bulk materials with protection, enhancement, and/or additional usefulness and attributes. Since materials can be modified or enhanced to possess different properties such as mechanical, thermal, or chemical to improve urban built environment functions, nanotechnologies have been widely included in functional coatings in recent years. Recent studies on functional coatings for green and smart buildings are summarized in this review paper. These comprised phase change materials, photocatalytic, hydrophilic, hydrophobic, solar reduction, and solar utilization coatings. This study offers a thorough overview of functional coating methods, from the production of raw materials through their application to building components.
