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.
