Abstract:Molecular level mixing process was developed for the fabrication of homogeneous carbon nanotube(CNT)/Inorganic nanocomposites instead of the conventional powder mixing process in order to solve the agglomeration of CNTs and weak interfacial bonding between CNTs and inorganic matrices. The CNT/Inorganic nanocomposite powders fabricated by molecular level mixing process consisted of homogeneously dispersed CNTs within inorganic powders. The morphologies of the CNT/Cu, CNT/Co nanocomposite powders show ideal composite microstructures, which displays that CNTs are homogeneously implanted in the powders. The CNT/Inorganic nanocomposite powders fabricated by the molecular level mixing process were consolidated into bulk CNT/Inorganic nanocomposite by spark plasma sintering process. The consolidated CNT/Inorganic nanocomposite shows homogeneous distribution of CNTs within the matrices. CNT/Cu and CNT/Co nanocomposites showed enhanced yield strength and Young’s modulus by homogeneous dispersion of CNTs and effective load transfer due to the strong interfacial bonding between CNTs and matrices. CNT/Co nanocomposite field emitters, fabricated by sintering of CNT/Co nanocomposite powders, showed excellent field emission properties with low turn-on field, high current density and homogeneous field emission due to low electrical resistivity by good interfacial bonding between CNTs and Co and homogeneous dispersion of CNTs in Co matrix.
