Evolution, Control, and Effects of Interface in CNT/Al Composites: a Review

This review summarizes the work carried out in the field of interface study in carbon nanotube reinforced aluminum (CNT/Al) composites. Much research work has been conducted to reveal the evolution of CNT/Al interface in producing the composite with the purpose of achieving uniform distribution of CNTs and tight interfacial bonding. The effect and principles of coating were reviewed along with the illustration of “intermetallic interphases” design. Different roles of CNT/Al interface in structural and functional application were elucidated, and the future work that needs attention was addressed.
