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.

The influence of surface modifications on the mechanical properties of epoxy-hexagonal boron nitride nanoflake (BNNF) nanocomposites is investigated. Homogeneous distributions of boron nitride nanoflakes in a polymer matrix, preserving intrinsic material properties of boron nitride nanoflakes, is the key to successful composite applications. Here, a method is suggested to obtain noncovalently functionalized BNNFs with 1-pyrenebutyric acid (PBA) molecules and to synthesize epoxy-BNNF nanocomposit

Super-strong carbon nanotube (CNT) fibers are fabricated by infiltration of the mussel-inspired underwater adhesives, poly(ethylenimine)-catechols (PEI-Cs). PEI-C mimics the amino acid sequence of mussel adhesive proteins in which catechols from 3,4- dihydroxyl-L-phenylalanine and amines from lysine are found. Weak interactions between CNTs are overcome by heat-induced, metal-catalyzed chemical crosslinking of catechol. PEI-C’s strong and versatile adhesion results in high-strength CNT fibers. D

Chemically bonded oxygen atoms at the carbon nanotube (CNT)/metal interface provide strong bonding between CNTs and a metal matrix (see picture). The origin of the enhanced mechanical properties of CNT/Cu is analyzed by the load-transfer concept and oxygen atoms are found to be a key factor in the construction of strong CNT/metal composites.
