Frequently asked questions Question What is the minimal particle size that can be obtained during milling in the planetary mills used? Answer The minimal particle size depends first of all on the material treated. Routine milling in planetary mills allows us to obtain submicron powders of the average particle size equal to several hundreds nanometers.
The process was conducted at a rotational speed of 400 rpm for 12 hours. Aggregated globular particles were obtained by dry milling due to the fast decrystallisation, whereas nanofiber dispersions were achieved in wet conditions. Interestingly, milling in the presence of PDMS led to the formation of nanosheets with a specific orientation.
