Preface: functional nanocomposite materials.

Functional nanocomposite materials are hybrid systems combining nanoscale fillers with a matrix, resulting in enhanced properties such as mechanical strength, thermal stability, and electrical conductivity. These materials are highly versatile, finding applications across a broad range of fields, including aerospace for lightweight, strong components, electronics for flexible and high-performance devices, healthcare for targeted drug delivery and tissue engineering, and environmental sectors for water purification and pollutant sensing. Their tunable properties make them ideal for addressing emerging challenges in various industries. This special issue entitled as "Functional Nanocomposite Materials" of Journal of Materials Science is a remarkable collection of invited and contributed papers on this topic, showcasing outstanding recent research results in this field.
