High-energy ball milling (HEBM) is a treatment of powders, which uses the action of the milling media to mix, disperse, activate and form composite structures [1–4]. The milling devices exist in various designs. Usually, they are divided into two groups: low-energy and high-energy mills [5]. The processes occurring during HEBM are deformation,

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.
