Properties Of Cellulose Nanofibril Produced From Wet Ball

Ball milling is an environmentally friendly and low-cost method of producing CNF because of its ease of use, relatively inexpensive equipment, its combination of friction, collision, shear, and other mechanical actions to reduce the crystallinity of cellulose, and its applicability to essentially all classes of materials (Zhang et al. 2018 ...

Effect Of Acid Hydrolysis And Ball Milling On Porous Corn

Highly crystalline porous starch has a fragile granule structure. Ball milling destroys crystallinity in both normal, porous, and cross‐linked or partially hydrolyzed starches. Particle sizes of 1–2m are obtained by milling dry starches for 48 h. Water absorption for milled starches is more than 200% (weight water/weight starch d.b.).
