Carbon nanotube/polyetheretherketone nanocomposites: mechanical, thermal, and electrical properties

High-temperature engineering thermoplastics are gaining growing interests as they not only provide a lightweight solution but also affect the manufacturing processes and efficiencies. Polyetheretherketone (PEEK) is a semi-crystalline one to meet such requirement, and has been widely used as the matrix for fiber-reinforced plastics and nanocomposites. Owing to their superior physical properties, carbon nanotubes (CNTs) can be introduced into PEEK matrix in order to further improve the performances. This article reviews the state of the art of CNT/PEEK nanocomposites, by focussing on the preparation method and their mechanical, thermal, and electrical properties. The enhanced stiffness, thermal stability, and conductive properties provide PEEK and its family members richer opportunities toward high-performance applications.

Automated summary

High-temperature engineering thermoplastics, such as PEEK, are being widely used as matrix materials for fiber-reinforced plastics and nanocomposites. The incorporation of carbon nanotubes (CNTs) into PEEK matrix enhances stiffness, thermal stability, and conductive properties. This opens up richer opportunities for high-performance applications of PEEK and its family members.
