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.
