What is Molybdenum disulfide?
Molybdenum Disulfide is a dry/solid lubricant powder, also known as molybdenite (principal ore from which molybdenum metal is extracted), and has the chemical formula MoS2. It is insoluble in water and dilute acids. The crystal structure is Hexagonal Lamellar, similar to graphite, Boron Nitride, and Tungsten Disulfide. It also has excellent film-forming properties and is an excellent lubricant in moisture-free environments below 400° C. MoS2 offers excellent lubricity properties in inert atmospheres and under high vacuum where other conventional lubricants fail. MoS2 also offers extreme pressure lubricant properties. MoS2 can withstand up to 250,000 p.s.i., making it extremely effective in applications such as cold metal forming. MoS2 is widely used as a dry lubricant additive in Grease, Oils, Polymers, Paints, and other coatings. MoS2 is available in particle sizes: 90 nm, 1.5 microns, 4.5 microns, and 12.5 microns. Larger sizes are possible as custom orders. Standard packing: 1 lb. plastic bag, 10 lbs. plastic bag, and 25 Kg (55 lbs.) in a small drum.
New and future applications of MoS2
Since the discovery of single-layer graphene in 2004, the field of 2D materials has seen several new classes of materials emerge. One of these is transition metal dichalcogenides (TMDs). These materials comprise one of the transition metals bound with one of the elements in Group 16. However, oxides are typically not classed as dichalcogenides. Molybdenum Disulfide (MoS2) is currently the most studied member of the TMD family. Similar to graphite, when MoS2 transitions from a bulk structure to a single-layer structure, the properties of this material undergo a significant change. The layers of the TMD can be mechanically or chemically exfoliated to form nanosheets.
The most striking change of MoS2
The most striking change when transitioning from bulk to single layer is the shift in the optoelectronic properties, with the material changing from an indirect bandgap semiconductor with a bandgap value of approximately 1.3 eV to a direct bandgap semiconductor with a bandgap value of approximately 1.9 eV. Due to the presence of a bandgap in this material, there are significantly more uses for MoS2 than other 2d materials such as graphene. Some areas in which MoS2 has already been applied include high on/off ratio field effect transistors due to low leakage currents, memristors based on layered TMD films, controllable spin and valley polarization, geometric confinement of excitons, tuneable photoluminescence, the electrolysis of water, and photovoltaics/photodetectors.
