Abstract:
A simple method allowing for simultaneous liquid-phase exfoliation of MoS2 crystals into few-layer sheets and colloidal formation of the exfoliated sheets is reported. This is enabled by using small molecular 1-pyrene-butyrate salts which provide a dual-role in the process, i.e., exfoliation enhancer and stabilizing agent of the MoS2 sheets.
