Keywords Carbon nanotubes (14) , Electrical resistance, Ultraviolet irradiation, Functionalization.

The electrical resistance of irradiated with ultraviolet carbon nanotubes were investigated. It is established that ultraviolet irradiation results in insignificant fuctionalization of carbon nanotubes surface, that doesn’t substantially affect on the nanotubes resistivity. It is shown that carbon nanotubes fuctionalization with strong oxidizers leads to a significant increase of resistivity by breaking electrinic system and localization of electrons by functional groups, and also to increase of contact resistance between the individual tubes by reducing the contact area between them
