Synthesis of graphene oxide from graphite by ball milling

2020-11-1  Oxidation of the graphite by the ball milling method was achieved adding potassium perchlorate and deionized water as a medium. Moreover, by ball milling energy was possible to get graphene oxide. This can be considered as an effective and enhanced method compared with Hummer's method due to processing time.

Ball Milling an overview ScienceDirect Topics

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

Graphene in Edge-Carboxylated Graphite by Ball Milling

Edge-carboxylated graphite (ECG) was produced by grinding pristine graphite in a planetary ball-mill machine. Transmission electron microscope was used to confirm the layers of graphene in ECG. The elemental analyses showed that the oxygen contents are different between ECG samples. The vibrational analysis of single- and five-layered graphene was conducted using
