dc.description.abstract© 2023, The Author(s), under exclusive licence to The Materials Research Society.Here, an ultrasonic-assisted ball milling exfoliation method to obtain 2D MoS2 and WS2 sheets was developed. We investigated the effect of rotational speed, milling time, and wet or dry milling agent. The yield, dimensions, and structural characteristics of the exfoliated MoS2 and WS2 sheets were investigated by different characterization techniques. To investigate the effect of ball rotation speed, samples were mixed with NaCl and milled at 150 rpm, 300 rpm, and 450 rpm for 2 h. Samples milled for 1 h, 2 h, and 4 h at 450 rpm were also prepared. Finally, the effect of the milling agent was tested milling the samples in Isopropanol. The best condition found was 2 h at 450 rpm in NaCl dry medium, with sheets of 1–4 layers with lateral size in the order of microns and showing high stable dispersions. Exfoliation yield with the best milling condition was 96% and 43% for MoS2 and WS2, respectively. Graphical abstract: [Figure not available: see fulltext.]
