Effect of ballmilling and graphene contents on the

Jan 15, 2017 · The reason may be that the accumulated energy during ballmilling is larger than the chemical energy of C C bond. In order to achieve a uniform dispersion of GNSs in the copper matrix and relatively complete graphene structure, the ballmilling time is selected as 5 h according to the analysis of experiment results.

Preparation of graphene by exfoliation of graphite using

Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multilayered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,Ndimethylformamide (DMF) and exfoliated by shearforcedominated ball milling carried out in a planetary mill.
