Effects of compressive strains on electrical conductivities of a macroscale carbon nanotube block
2007
Applied Physics Letters
Preserved Fulltext
A macroscopic block ͑ϳ9 mm 3 ͒ of aligned carbon nanotubes ͑CNTs͒ was grown by chemical vapor deposition and its simultaneous electrical conductivity and compressive strain responses were measured parallel and perpendicular to the CNT alignment. The block exhibits elastic moduli of 0.9 and 1.6 MPa for compressive strain of Ͻ20% in parallel and perpendicular configurations, respectively. The electrical conductivity increases with increasing compressive strain in both configurations. The
