This study examines the ball-milling of CVD-processed multi-wall carbon nanotubes for cutting and opening their tips. Results show that dry milling causes nanotubes to rapidly collapse, hence transforming into graphite structure, while wet milling with some organic compounds effectively shortened and opened the nanotubes. Carbon-based milling agents are known to alter surface .
Precision Milling of Carbon Nanotube Forests Using Low . Carbon nanotubes (CNTs) and graphene are carbon-based nanomaterials that have attracted significant attention because of their superior strength, durability, thermal, and electrical properties.

In this paper, in situ Al 4 C 3 and carbon nanotubes (CNTs) hybrid-reinforced aluminum matrix composites were prepared by a two-step ball milling (TSBM), consisting of a 24-h long-time ball milling (LTBM) and a 6-h short-time ball milling (STBM). During LTBM, most of the CNTs were seriously damaged, and many amorphous carbon atoms derived from these damaged defects would react with .

We have synthesized multi-wall carbon nanotube (MWCNT)-reinforced Al matrix composites. The Al/MWCNT composite powders were prepared by ball milling using pristine Al or ball-milled Al powders as starting materials. The composite powders were consolidated by a conventional cold-compaction, followed by sintering. Uniform dispersion of individual MWCNTs within the matrix was in particular a ...
This paper focuses on the optimization of ball milling as a dry mixing method and comparison with the wet method for manufacturing phenolic/multi-wall carbon nanotube (MWCNT) composites. In the ball milling, the effect of milling-time on the properties of composites containing functionalized and pristine MWCNT in two MWCNT concentrations has been investigated.

Debundling of single-walled carbon nanotubes (SWNTs) has been mostly limited to liquid-phase exfoliation. Since the SWNTs in dispersion are prone to aggregate and precipitate gradually during their storage, a solid-phase method that provides debundled SWNTs as "stock solid" is highly required. Herein, we report on a solution to this issue, which is based on solid-phase ball milling.
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.
For all nanocrystalline materials prepared by high-energy ball milling synthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for high-energy ball milling ...
