Carbon‐nanotube‐reinforced Cu matrix nanocomposites have been fabricated by molecular‐level mixing of functionalized carbon nanotubes (CNTs) with Cu ions, followed by spark plasma sintering. The compressive strengths and Young's moduli of CNT‐reinforced nanocomposites are considerably higher than those of the Cu matrix due to the homogeneously dispersed CNTs embedded in the Cu matrix (see Figure).
