Schematic depiction of (A) Pluronic and (B) Tetronic block copolymers on the surface of a single-layer MoS2 flake. The amphiphilic Pluronic/Tetronic block copolymers adsorb non-covalently to the surface of MoS2 and prevent the agglomeration of the exfoliated flakes by acting as a surfactant and providing steric repulsion.
