Exfoliation of graphene sheets via high energy wet

01/05/2017  The high boiling point makes them suitable for milling of graphite for a long time (60 h), and high milling speed (400 rpm) using the planetary ball mill that well known as it has not a cooling system. Since the high milling speed for long time raises the mechanical energy applied to the sample, then the production of excessive heat is the result of these conditions, thereby the high boiling ...

Ball mill - Wikipedia

High-energy ball milling. A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel ...

Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling. Longer milling times enhanced the breaking of the hydrogen ...
