  • Preparation of short carbon nanotubes by mechanical ball ...

    Short multi-wall carbon nanotubes (MWNTs) with open tips were obtained by mechanical ball milling. The microstructure characteristics of MWNTs before and after ball milling were checked by transmission electron microscopy (TEM). The effect of ball milling on the hydrogen adsorption behavior of the MWNTs was studied.

  • Carbon Nanotubes History And Production Methods Cheap Tubes

    Ball Milling. Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.

    Ester Vázquez 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.
