Bulk crystalline MnPS 3 was prepared performing a solid-state reaction 2 and exfoliated through chemical intercalation in two steps with K + and Li + ions. Furtherly, the obtained material was exfoliated through probe assisted sonication. The so obtained material was resuspended in water (MnPS 3 @H 2 O) in order to obtain a 2D ink of fully accessible flakes. Alternatively, two different capping agents were added, i.e.: polyvinylpyrrolidone (PVP) and polyethylenimine (PEI), 22 being both well-known capping agents for stabilizing nanomaterials in aqueous solutions. The use of these polymers gave rise to MnPS 3 @PVP and MnPS 3 @PEI suspensions, respectively. These three systems were fully characterized and compared with each other.
