Two are better than one : A mixed‐solvent method for liquid exfoliation of MoS 2 , WS 2 , and BN nanosheets is presented. Although ethanol and water are both poor solvents for this process, ethanol/water mixtures of appropriate composition, which can be predicted on the basis of Hansen solubility parameters, result in efficient exfoliation (see schematic) to give highly stable suspensions.
