Utilization of cellulose micro/nanofibrils as paper additive

The fiber width of the cellulose micro/nanofibrils was analyzed using a FE-SEM (JSM-7610F, JEOL, Tokyo, Japan) to ensure the material was ground to the nano-scale after micro-grinding. Wet micro/nanofibril pads were prepared as test specimens for the measurement of fiber width using the vacuum filtration system.
