英文摘要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. milling with water or pdms caused partial dispersion of nanofibers. milling with pdms formed micro-platelets < 1 a mu m thick with slight decrystallization. remarkably, nanoscale particles isolated from pdms-milled cellulose by sonication in ethanol contained cellulose nanosheets, typically 0.1-10 a mu m wide and 4.2 nm thick, apparently formed by monolayer association of elementary fibrils. tem and electron diffraction revealed crystalline nature of nanosheets, with specific orientation of (110) plane or (200) plane perpendicular to the sheet plane. a possible mechanism of the nanosheets formation is proposed, in which the elementary fibrils are aligned parallel by mechanical impacts.
