AN EXPERIMENTAL STUDY ON SURFACE MODIFIER ASSISTED EXFOLIATION OF MOLYBDENUM DISULPHIDE IN A MIXED SOLVENT

Molybdenum disulphide (MoS2) is a layered transitional metal dichalcogenide that exhibits unique properties when isolated into one or few layers. MoS2 finds applications in electronics and optoelectronics, along with the ability to act as host materials to polymers. In this paper, we report the successful exfoliation and modification of MoS2 with Lithium salt of 6 amino hexanoic acids (Li-AHA) in a mixed solvent of N-Methyl-2-Pyrrolidone (NMP) and deionized water. The X-ray diffraction studies showed reduction in size accompanied by increased strain, which indicates exfoliation. Photoluminescence was proved for the exfoliated sample using photoluminescence spectroscopy. The antimicrobial study results showed that the exfoliated MoS2 had better zone of inhibition than pristine MoS2.
