Various methods can be utilized to conduct polymer mechanochemistry, such as single molecule force spectroscopy [5], ultrasonication [6], and ball-mill grinding (BMG) [7]. With BMG, polymers experience various mechanical stresses due to being trapped in ball-ball and ball-vessel collision events, which can lead to chain scission or …
In this work, the deconstruction mechanism of corn stover cell wall polymers during ball milling was evaluated. The characterization showed that ball milling not only brought about the dissociation of the cross-linked cellulose-hemicellulose-lignin complex but also led to the depolymerization of the cell-wall polymers especially the carbohydrates.
