چکیده انگلیسی
The electrical conductivity and mechanical characteristics of nanocomposites from pristine and doped single wall carbon nanotubes (SWNT) with polymethylmethacrylate (PMMA) were measured. In highly purified HiPCO SWNT, a percolation threshold as low as 0.17 weight percent has been found. The conductivity value at saturation is about 17Â S/cm. If the purified HiPCO SWNTs are doped with SOCl2, the percolation threshold does not change but the saturation conductivity rises to about 100Â S/cm. The mechanical properties were investigated for the PMMA composite mixed with SOCl2-doped SWNT. A small content of doped nanotubes dramatically changed Young modulus, toughness and tensile strength as well.
