“…Carbon nanotubes (CNTs) have received significant attention as a material for the production of advanced engineering composites due to their unprecedented mechanical and thermal properties like ultra-high elastic modulus ( 1 TPa), tensile strength ( 150 GPa) and thermal conductivity (3000-6000 W/mK) in combination with an extraordinarily low coefficient of thermal expansion ( 10 6 K 1 ), which may offer high mechanical, electrical and thermal performances unattainable for common materials [1][2][3]. Extensive researches have shown that the CNTs have proven themselves as cold field emitters [4][5][6], supercapacitors [7], solar cells [8], sensors [9], etc.…”

A study of the electrical conductivity of mechanical mixture of both the carbon nanotubes (CNTs) (with work function of 4.7 eV) and the Cu and Al metal microparticles (with lower work functions of 4.2 and 4.0 eV, respectively) under compression is provided. As shown, the electrical conductivity of the Al and Cu powders is essentially increased with addition of the CNTs (up to 30 wt.%). The electrical conductivity dependence on the density of a powder mixture of Al with CNTs is characterized by a deep minimum observed at the concentration of 9.6 wt.% CNTs. This feature is a result of the electrons' localization in the Al 2 O 3 film formed on a sample surface. A number of factors, in particular, a shift of the Fermi level of the CNTs deep into the valence band, explain the sharp decrease in the electrical conductivity of the Al CNTs composite, unlike the Cu-based composite.
