We report the synthesis of superhydrophobic two-dimensional (2D) transition metal dichalcogenides by modulation of the degree of atomic defects. The presence of atomic vacancies in 2D molybdenum disulfide (MoS 2) nanoassemblies dictated hydrophilic-to-hydrophobic transition and subsequent cell adhesion.
We introduced a new concept to the control of wetting characteristics by modulating the degree of atomic defects of two-dimensional transition metal dichalcogenide nanoassemblies of molybdenum disulfide. This work shed new light on the role of atomic vacancies on wetting characteristic that can be leveraged to develop a new class of superhydrophobic surfaces for various applications without altering their topography.
