Preparation of graphene via wet ball milling and in situ

Functionalized graphene (G-MA) was prepared by a facile wet ball milling strategy, which achieved exfoliation and functionalization of graphite simultaneously. The G-MA showed excellent dispersion in water and polar solvents. Thus, a G-MA coating was prepared from G-MA in mixed solvents (H2O–ethanol) without

One-Step Ball-Milling Preparation of Highly Photocatalytic

We prepared CoFe 2 O 4 –RGO (RGO: reduced graphene oxide) composites by ball-milling without using toxic chemical reagents and high-temperature heat treatment. The exfoliation and reduction of graphite oxide and anchoring of CoFe 2 O 4 nanoparticles on graphene sheets were accomplished in one step.

One-step preparation of graphene nanosheets via ball milling

Jan 06, 2016 · An improved method for mass production of good-quality graphene nanosheets (GNs) via ball milling pristine graphite with dry ice is presented. We also report the enhanced performance of these GNs as working electrode in lithium-ion batteries (LIBs). In this improved method, the decrease of necessary ball milling time from 48 to 24 h and the increase of Brunauer–Emmett–Teller surface

Effect of ball-milling and graphene contents on the

Jan 15, 2017 · With increasing the ball-milling time, the dispersion of GNSs in the copper matrix becomes better. However, more defects or disorder structures appear in GNSs. The reason may be that the accumulated energy during ball-milling 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 ball-milling time is selected as 5 h according to the analysis of experiment results.
