Due to its unique layered structure and extremely low coefficient of friction (0.03–0.06), molybdenum disulfide is widely utilized as a solid lubricant.
It exhibits excellent mechanical flexibility, making it suitable for the fabrication of flexible displays, sensors, and wearable electronic devices.
Leveraging its direct bandgap properties, it can also be employed to fabricate high-performance photodetectors, light-emitting diodes (LEDs), and solar cells.
The layered structure of molybdenum disulfide facilitates the intercalation and deintercalation of lithium ions; thus, it serves as an electrode material additive that significantly enhances the specific capacity and cycling stability of lithium-ion batteries. Furthermore, its high specific surface area and electrical conductivity render it a high-performance electrode material for supercapacitors.
Possessing excellent biocompatibility and low toxicity, it is currently being explored for applications in fields such as drug delivery carriers, bioimaging, and antimicrobial agents.
