Carbon nanotube (CNT)/Ag nanocomposites were synthesized by an ultrasonic process. Dispersion of aggregated CNTs and synthesis of both Ag nanoparticles and Ag/CNT composite particles were executed by ultrasonic treatment. Dispersibility of Ag nanoparticles improved with the combined use of a dispersant, which led to improved densification upon sintering. In addition, synthesis of nanosize Ag particles allowed sintering of the CNT/Ag nanocomposites at 300°C, with a resulting electrical resistivity of 2.46 μΩ·cm.
