A comparative analysis of ball-milled biochar, graphene oxide, and multi-walled carbon nanotubes with respect to toxicity induction in Streptomyces. Journal of Environmental Management 2019, 243, 308-317. DOI: 10.1016/j.jenvman.2019.05.034. Xiaoyun Xu, Yulin Zheng, Bin Gao, Xinde Cao.
Additionally, nitrogen functional groups were also introduced by ball milling the carbon composite together with melamine. The oxygen groups on the surface of the carbon nanotubes favor their dispersion into the precursor mixture and the formation of a more homogenous carbon structure with higher mechanical strength.
We present a fast method to prepare hybrid materials of polyaniline (PAni) with carbon nanotubes (CNTs, both undoped and nitrogen-doped) by ball milling without solvents or strong oxidants. PAni forms nanoparticles, attached to CNTs in a nanocomposite structure, with the nanotubes .

High energy ball milling (HEBM) was utilized, as an innovative process, to incorporate carbon nanotubes (CNTs) into a polyethylene (PE) matrix avoiding: high temperatures, solvents, ultrasonication, chemical modification of carbon nanotubes. Composites with 1, 2, 3, 5, and 10 wt % of carbon nanotubes were prepared.
Ball milling the carbon nanofibers prior to adding to polypropylene provides the lowest highest electrical conductivity because the fiber length is similar to the non-ball milled fiber, but the dispersion is better. Ball milling the carbon nanofibers for 10 minutes shortens the fiber length too much to decrease the resistivity in the polypropylene.

The synthesis of new materials containing multi-walled carbon nanotubes (MWCNTs) and the microstructure of alumina particles were investigated and characterized. The MWCNTs and alumina particles were ground under both the dry and wet conditions with various rotation speeds (200–400 r/min) in planetary ball milling machine, and their ...
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.
