ball-milling of graphite and muilti-wall carbon nanotubes

Feb 15, 2011 Ester Vzquez and colleagues, Universidad de Castilla-La Mancha, Spain, report the use of a planetary retsch ball mill, which consisted of stainless steel balls within a grinding bowl, to cut and disperse single-walled nanotubes (SWNTs). Air, high rotational speeds, and long milling times led to partial or almost total destruction of SWNTs.

Sep 01, 2008 The effects of ball milling on lithium (Li) insertion/extraction properties into/from single-walled carbon nanotubes (SWNTs) were investigated. The SWNTs were synthesized on supported catalysts by thermal chemical-vapor deposition method, purified, and mechanically ball-milled by high-energy ball milling. The purified SWNTs and the ball-milled SWNTs were …
