Fabrication and Characterization of Carbon Nanotube–Titanium Nitride Composites with Enhanced Electrical and Electrochemical Properties

This work reports the fabrication and the characterization of a new composite consisting of multiwalled carbon nanotubes (CNTs) and conducting titanium nitride (TiN) with a higher specific surface area ( S BET ), enhanced electrical conductivity (σ), and specific capacitance. With increasing CNT content, the electrical conductivity and electrochemical performance of the CNT–TiN composites gradually increase. In the presence of 5 wt% (12.0 vol%) CNTs, the electrical conductivity and the weight‐specific capacitance of CNT–TiN composite are increased by 3.6 times and 54.8% compared with pure TiN, respectively.
