In this work, a separation of arc-grown single-walled carbon nanotubes (SWNTs) over conductivity type has been performed with an aqueous two-phase separation method. The separated fractions were used to synthesize copper chloride (CuCl) at SWNTs hybrid materials. These nanohybrids were studied using UV-vis-NIR optical absorption and Raman techniques. The changes in electronic and optical properties of functionalized SWNTs were revealed. A significant p-type doping of SWNTs by CuCl was considered as a main reason for modification of nanotube optical properties.
