Abstract 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 …Web

High-energy ball milling is a type of mechanical grinding of materials. This process can be conducted in a dry (without solvents) or wet (with solvents) fashion. Laboratory-scale ball milling (5–100 mL scale) is a batch process, whereas industrial ball mills can be operated in a continuous mode, thus offering a very high synthesis throughput.Web
