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 …

multiwall carbon nanotube reinforced aluminum matrix

In the present work, we employed low-energy ball milling in dry and wet conditions to synthesize Al-MWCNT composites with homogeneous distribution of reinforcing phases. Dry ball milling easily resulted in the collapse of MWCNTs as well as a cold welding of constituent particles. Wet milling, on the other hand, induced a homogeneous distribution of MWCNTs and matrix phase
