Communication—Conductive Paintable 2D Layered MoS 2 Inks

Conductive and paintable inks of 2D layered MoS 2 with aspect ratio-dependent conductivity are demonstrated. Using ultrasonically assisted solvent-exfoliation of MoS 2 , high concentration 2D and few-layer suspensions become inks that provide coherent films when painted. Conductivity of paintable 2D...

Summary:Conductive and paintable inks of 2D layered MoS 2 with aspect ratio-dependent conductivity are demonstrated. Using ultrasonically assisted solvent-exfoliation of MoS 2 , high concentration 2D and few-layer suspensions become inks that provide coherent films when painted. Conductivity of paintable 2D MoS 2 inks can be modulated by length and width, where the conductivity is linked to the painting direction. Reducing the painted film width, increases conductivity for similar length, and the films conductivity is aspect ratio-dependent. Inks of solvent-exfoliated 2D MoS 2 can be painted without polymeric additives.
