The ball‐milling of cellulose fibers and recrystallization ...

A study has been made of the effect of fine structure on the decrystallization process which results from the ball‐milling of cellulose. The rate of decrystallization is sensitive to the type of fine structure and is accelerated by the presence of moisture. The extent of chain degradation was greater in air atmosphere than in carbon dioxide, suggesting that mechanically induced free radical ...

Effects of ball milling on the structure of cotton cellulose

17/01/2019  The approximately one liter steel jar was chromium plated and 500 mL of stainless steel balls 0.25 in. (~ 6 mm) in diameter were employed. This is considered to be a “vibratory” ball mill in contrast to the planetary type. The cellulose samples milled for 15 min, 45 min and 120 min were respectively labeled as BMC-15, BMC-45 and BMC-120.

Effects of ball milling on the structure of cotton cellulose

17/01/2019  In this work, cotton cellulose was ball-milled for 15, 45 and 120 min. Multiple approaches concurred that the cellulose crystals were progressively destroyed by the blunt-force impacts of vibratory ball milling. The fibers were split open and broken into small bits, the molecular weights decreased, and the cellulose was oxidized on a small scale, as shown by an increase in carbonyl groups ...
