Abstract: We carried out in situ Young's modulus and electrical resistivity measurements on macroscopic oriented ropes of singlewall carbon nanotubes under ultraviolet irradiation. Increases of both the electrical conductivity and the mechanical strength have been observed. These phenomena are explained by the photochemistry between the functional groups on the surface of singelwall nanotubes and dimethyl-formamide molecules are trapped between the nanotubes. In contrast to high energy electrons during electron irradiation, the photon energy of the ultraviolet irradiation is not sufficient to displace the carbon atoms in the nanotube, therefore the graphitic structure of the tubes remains intact.
