Nanocomposite materials

Definition

Nanocomposite materials are advanced materials that combine traditional matrix materials, like polymers, metals, or ceramics, with nanomaterials to enhance their properties. The incorporation of nanomaterials at the nanoscale (1 to 100 nanometers) allows for improved mechanical strength, thermal stability, electrical conductivity, and barrier properties compared to their conventional counterparts. This makes nanocomposites highly desirable in various applications, including electronics, aerospace, automotive, and biomedical fields.
