Milling was then performed in 80% ethanol for 30–120 minutes using a highenergy 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 intrafibre swelling.
