The book chapter provides an overview of the use of nanocomposites in architecture. It starts with an introduction that explains how architecture has always reflected the technological advances of its time and how nanocomposites have emerged as a promising field for advancing the capabilities of the architecture. The chapter then provides an overview of nanocomposites, including their properties and manufacturing methods. The properties of nanocomposites are highly dependent on the type of filler and matrix material used, as well as the manufacturing process. The chapter then delves into the specific applications of nanocomposites in architecture, including structural, energy-efficient, and aesthetic applications. The use of nanocomposites in these applications can lead to reduced material usage, increased design flexibility, improved structural performance, and improved energy efficiency. Through case studies, the chapter examines successful examples of the use of nanocomposites in architecture and discusses their advantages and limitations. Finally, the chapter explores the potential future applications of nanocomposites in architecture and discusses the challenges and opportunities for research and development in this exciting field. The book chapter aims to provide architects, researchers, and engineers with a comprehensive overview of the potential of nanocomposites in architecture, exploring new avenues for building design and creating more sustainable, efficient, and visually appealing structures.
