dec 05, 2009 arkema france reveals in u.s. patent 7,622,059 a method for synthesis of carbon nanotubes of the highest carbon purity by combining the process of vapor phase chemical deposition. with ball milling. the nanotubes produced can be used to advantage in all known applications of carbon nanotubes.
the aim of our experiments was the production of helically coiled carbon nanotubes selectively. the influence of catalytic particles prepared by ball milling was investigated on the growth. of coiled carbon nanotubes under conditions. for qualitative characterization of carbon deposit on the surface, the products were imaged by transmission and scanning electron microscopy

dec 15, 2012 the significant advantage of this method is that it can be readily implemented commercially. ball milling can be used to make carbon nanotubes and boron nitride nanotubes. It is a preferred method for preparing metal oxide nano crystals like cerium and zinc oxide 10.
ball milling has attracted much attention as a promising method for modifying carbon nanotubes, namely to adjust their lengths and to open the closed ends 2122 23, increasing their specific
swnts to l.7 after min of milling. the irreversible capacity decreased from Li to Li electro.2 1.3 microscopy, raman and x-ray diffraction measurements indicated that ball-milling induced disorder within the bundles and fractured the nanotubes. published by elsevier science b.v. intercalation compounds of carbon
the current paper presents a new approach of attaining the optimum grinding condition of a planetary ball mill and simple method for purifying multi-walled carbon nanotubes to investigate the dispersion characteristics of mwcnts. this work

In this paper, to improve the poor wettability between the carbon nanotubes and metal matrix, the mechanical alloying technique by the ball milling method was employed. also, the cnts were pre-coated to improve the agglomeration of the cnts with copper powder. the main aim of this work
feb 12, 2013 the dependence of multiwall carbon nanotube length distribution and some nitrogen derived morphological descriptors on various planetary ball milling process parameters was investigated. ball milling was found to cut nanotubes into smaller pieces, narrow their length distribution and increase their specific surface area and surface fractal dimension.
