Scientists Discover New Method of Moly Disulfide Exfoliation

AZoNano reported that scientists at the National University of Singapore have developed a way to “chemically exfoliate molybdenum disulfide crystals … into high quality monolayer flakes with higher yield and larger flake size than current methods.”

The flakes can be made into a printable solution that can be used in electronics and printable photonics.

As quoted in the market news:

This breakthrough … has generic applicability to other two-dimensional chalcogenides, such as tungsten diselenide and titanium disulfide, and results in high yield exfoliation for all of these two-dimensional materials.

Commenting on the significance of the findings, Prof Loh [Kian Ping, who led the breakthrough,] said, ‘At present, there is a bottleneck in the development of solution-processed two dimensional chalcogenides. Our team has developed an alternative exfoliating agent using the organic salts of naphthalene and this new method is more efficient than previous solution-based methods. It can also be applied to other classes of two-dimensional chalcogenides.’

‘Considering the versatility of this method, it may be adopted as the new benchmark in exfoliation chemistry of two-dimensional chalcogenides,’ he added.
