| Summary: | Using the equipment of the Russian-German channel of the RGL
station (BESSY II, Germany), the Kratos Axis Ultra DLD laboratory
spectrometer and the transmission electron microscope, data are
obtained on the chemical state of MWCNTs and their structure
after irradiation with a pulsed ion beam of nanosecond duration. It
is shown that pulsed ion irradiation leads to the formation of new
structural formations: thin nanotubes with an outer diameter of
~5 nm, structures up to ~ 20 nm in size, consisting of encapsulated
iron clusters in a graphite shell, and also of a onion-like carbon
with a characteristic size of ~5 nm. The formation of new structures
is one of the reasons for the increase in the fraction of carbon
atoms in sp3-hybridized in the surface layer of MWCNTs. |
