Macroscopic carbon nanotube assembly/silicon carbide matrix composites produced by gas phase route

Macroscopic carbon nanotube (CNT) self-assemblies are attractive in the field of high-performance composites for taking full advantage of outstanding physical and mechanical properties of individual CNTs at macroscopic level. In this study, macroscopic SiC ceramic matrix composites (CMCs) containing CNTs (CNT/SiC) based on the macroscopic CNT self-assemblies were fabricated using ice-segregation-induced self-assembly technique and chemical vapor infiltration process. The microstructure, macromechanical properties, electrical conductivity, and electromagnetic shielding effectiveness of the fabricated CNT/SiC composites were studied systematically.Graphical abstract
