24.02.2021· Ball milling are highly destructive on crystallinity, especially vibratory ball milling that can be used to produce amorphous cellulose (Yao et al. 2020). Although planetary ball milling that was used in this study is much slower and less destructive on crystallinity than vibratory ball milling, it still led to the most significant drop in the CrI of BSKP fibers among the several mechanical treatments in this …
