摘要

The raw single wall carbon nanotubes (SWCNT) were chemically and thermally treated and then milled in ball mill. After this SWCNT were irradiated by electron beam with energy 2.3 MeV up to fluence 10~(14) e~-/cm~2 at room temperature. Then SWCNT were saturated with hydrogen at pressure 5 bar and quenching down to the temperature 78 K. The sorption capability was measured by means of mass-spectroscopy and volumetric methods. The double increasing of mass hydrogen content in electron bombarded SWCNT was showed comparatively with non-irradiated samples.
