Universidad de Zaragoza Microwave-driven exfoliation of bulk 2H-MoS[sub]2 after acetonitrile prewetting produces large-area ultrathin flakes with exceptionally high yield 2023 Access copy available to the general public Unrestricted 2D materials display exciting properties in numerous fields, but the development of applications is hindered by the low yields, high processing times, and impaired quality of current exfoliation methods. In this work we have used the excellent MW absorption properties of MoS2 to induce a fast heating that produces the near-instantaneous evaporation of an adsorbed, low boiling point solvent. The sudden evaporation creates an internal pressure that separates the MoS2 layers with high efficiency, and these are kept separated by the action of the dispersion solvent. Our fast method (90 s) gives high yields (47% at 0.2 mg/mL, 35% at 1 mg/mL) of highly exfoliated material (90% under 4 layers), large area (up to several μm2), and excellent quality (no significant MoO3 detected). info:eu-repo/grantAgreement/EUR/ERC/ERC-AdG-742684 info:eu-repo/grantAgreement/EUR/ERC/ERC-PoC-842606 info:eu-repo/grantAgreement/ES/MINECO/CTQ2017-86060-P info:eu-repo/grantAgreement/ES/MINECO/PID2020-116661RB-I00 info:eu-repo/grantAgreement/ES/MINECO/PID2021-127847OB-I00 info:eu-repo/grantAgreement/ES/MINECO/SEV-2016-0686 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 15.8 2023 CHEMISTRY, PHYSICAL 14 / 178 = 0.079 2023 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 11 / 141 = 0.078 2023 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 15 / 231 = 0.065 2023 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 27 / 439 = 0.062 2023 Q1 T1 4.593 2023 Engineering (miscellaneous) 2023 Q1 Physics and Astronomy (miscellaneous) 2023 Q1 Nanoscience and Nanotechnology 2023 Q1 Materials Science (miscellaneous) 2023 Q1 26.0 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Laborda, M.
