The use of the ball mill resulted in a non-uniform and random breaking of the cellulose fibers. Some fibers have better defibrillation, while others remain micrometric in size. In some FE-SEM images, it is possible to observe some regions have a quasi-circular shape, for example, in 4 M, 1 M-20U, 2 M-20U, and 4 M-20U.

Ball Milling. Cellulose materials were wet ball-milled with a PQ-N2 planetary ball mill (Livingston, NJ, USA). The enzymatically treated fibers were diluted to 1.0 wt% and then agitated by a mechanical blender for 10 min. Then 150 g of the diluted fibril slurry were put into an agate jar of 500 mL capacity.

Ball milling. One gram of cellulose was milled in a planetary ball mill (Pulverisette 7, Fritsch, Germany), using 45 mL zirconia pot with 7 zirconia balls of 15 mm diameter. It took 5 min for rest after every 20 min of operation to release the heat. Milling time was 1 h, 2 h, 4 h, 8 h, 12 h, 24 h at 150 rpm. Characterization

First, we conducted the hydrolysis of cellulose using ball-mill or heat, and compared the oligomer products of the two systems. Ball-milling H 3 PO 4-impregnated cellulose gave an off-white solid powder having 65% solubility in water. As cellulose is insoluble in water even in amorphous form, the solubility indicates the formation of water ...

And ball milling can further dissociate the cross-linked cellulose–hemicellulose–lignin complex and depolymerize the cell wall polymers, which reduce the recalcitrance of plant cell wall and therefore may potentially improve the efficiency of EH. However, ball milling is an energy-intensive process, and a comparison between the increased ...
