Carbon nanotube (CNT) characteristics, besides the processing conditions, can change significantly the microwave absorption behavior of CNT/polymer composites. In this study, we investigated the influence of three commercial multi-walled CNT materials with various diameters and length-to-diameter aspect ratios on the X-band microwave absorption of epoxy …
Carbon nanotubes have high specific surface area and because of this they generally tend to hang together to form clusters and convoluted structures [6]. Using ultrasonic CNTs are mechanically separated in the homing solution [7]. Dispersion of Multiwalled Carbon Nanotubes in Aluminum Powders With Ultrasonic and Ball Mill Attrition

Dispersion of multiwalled carbon nanotubes in aluminium powders with ultrasonic and ball mill attrition. International conference on mechanical, automotive and material engineering (ICMAME'2012) Jan. 7-8, 2012 Dubai.
These powders would be used as precursors for subsequent consolidation to generate bulk CNT-Al composites. Hence controlling the initial powder characteristics prior to high temperature consolidation is important. Up to 48 h of milling was employed to investigate the effect of milling time on the particle size, morphology and CNT dispersions.
In this work, a cost effective and easy method to prepare N-doped carbon nanotubes by ball milling was developed, which avoids the use of solvents and production of …

Composite materials on the basis of A5 aluminum containing 0.01–0.1 wt % of carbon nanotubes (CNT) were obtained. The composite materials were fabricated by sand casting. Carbon nanotubes were added to the aluminum melt in the form of powdered mixture preliminarily produced using an AGO2S planetary ball mill. It was demonstrated that the CNT additions …
The effects of ball milling on cup-stacked carbon nanotubes are summarized as follows. Two different cleavage modes are considered, based on TEM observations. It is expected that the bending mode plays the main role in cleaving carbon nanotubes from the viewpoint of the cup-stacked morphology of these carbon nanotubes.
In this research paper, Multiwalled carbon nanotubes (MWCNTs) reinforced with Al2024 were ball milled for homogenization of powder. Nanocomposite was developed using MWCNT reinforcement having 0.5%, 1.5%, and 2.5% weight percentage mixed with Al2024 by powder metallurgy technique. Samples were compacted using a hydraulic press and sintered.
Knowing the extraordinary properties of carbon nanotubes, it seems that copper-based composites reinforced with small amount of carbon nanotubes, resulted in improved mechanical properties. Hence, carbon nanotube reinforced copper matrix nanocomposites are fabricated by hot-press sintering of high energy ball milled copper/carbon nanotube powders.
This study investigated the effect of three different ball materials on the metal-based carbon nanotube (CNT) composites used as surface coatings on metal-powder to fabricate high-quality nanocomposites. The effect of ball material, different rotation speeds, and milling times on the coating characteristics of the metal-based nanocomposite were studied.
The aim of the paper is to investigate the effect of size of multiwalled carbon nanotubes (MWCNTs) as additives for dispersion in gear oil to improve the tribological properties. Since long pristine MWCNTs tend to form clusters compromising dispersion stability, they are mildly processed in a ball mill to shorten the length and stabilized with a surfactant before …
