Abstract Details

In recent years, two dimensional (2D) materials such as Molybdenum Disulfide (MoS2) have been theoretically proven to exhibit unique properties such as extreme mechanical flexibility, high electron mobility properties, and large tunable band gaps. If created, 2D materials have the potential of revolutionizing the flexible electronics market. Unfortunately, mechanical or chemical exfoliation and chemical vapor deposition (CVD) have been unable to synthesize a large area, defect-free film. This work examines a new method of fabricating a film of 2D MoS2 using additive manufacturing. Instead of printing MoS2-based inks directly, this study uses aerosol jet printing of self-assembling peptides to bond to high quality 2D flakes via selective molecular attachment, thereby creating a film of MoS2. This technique poses several advantages to direct printing with particle-based inks, such as overcoming nozzle clogging due to nanomaterial aggregation and decoupling of particle size from printer nozzle diameter. Specifically, we developed an optimized process for maximizing the amount of MoS2 flakes on a surface, based on a series of Design of Experiments (DoE) methods used to characterize the binding interactions between the substrate, peptide, solvents, and MoS2 flakes. The proposed procedure minimized the overall variability for MoS2 film fabrication and increased robustness against film stress.
