jun 22, 2020 morphology studies of mwcnts nanofluids were carried out by using a sem and tem methods to characterize the surface deformity of mwcnt structure and extent of defect formation, respectively. FT IR and xrd methods were used for the identification of different functional groups and crystalline nature of pristine, ball milled and oxidized mwcnt dec 12, 2014 the ball-milling of mwcnts under impact mode usually resulted in the formation of an amorphous phase, whereas that under friction mode induced the fattening of nanotubes. the results showed that a variety of carbon nanomaterials could be obtained by the proper controlling of ball milling.Get Price
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 as well as ambient gas can be problems for high-energy ball milling jun 29, 2016 conclusion 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 12. mechanism OF grain size reduction 13.Get Price
feb 03, 2012 multiwalled boron nitride nanotubes were produced in high yield by jun Yu et a by using a ball milling-annealing method. these thin boron nitride nanotubes with a diameter less than nm were produced by ball milling-annealing method in which amorphous boron was first ball-milled for 150 in a NH atmosphere and subsequently annealed in NHGet Price
