Cellulose nanosheets similar to those obtained by milling with silicone oil (Zhao et al. in Cellulose 23:2809–2818, 2016) were obtained by mild additive-free milling followed by dispersion in ethanol. Typical nanosheets were of 4 nm thickness, possibly formed by monolayer association of elementary fibrils. The thickness decreased with prolonged milling to 2 nm or less, and the thinnest sheets observed...
The nanoscale structural changes of crystalline cellulose by mechanical milling was studied by high-resolution microscopy (AFM, SEM, TEM). We examined influence of environment [dry, water, silicone oil (PDMS)] on cellulose milling, finding their characteristic effects on microscopic morphology of the products. Dry milling of cellulose gave aggregated globular particles with fast decrystallization...
