Ball milling cellulose

Update date: Dec 30

Mar 01, 2021 The ball milling process grinds the starting material into a powder form (Wan, Jiao, Bao et al., 2019), which can then be used to separate nanowhiskers and nanoparticles from the cellulose microfibers' bundles (Baheti, Abbasi, & Militky, 2012; Mattonai et al., 2018)
