Nanosheets characterization for MoS₂ dispersions in water.

<p>Fig 1-A, SEM image of vacuum filtrated dispersion onto polycarbonate membrane, Fig 1-B, TEM image of nanosheets, Fig 1-C, AFM image of a nanosheet deposited on silicon wafer with the thickness profile on the inset. Fig 1-D, is a photograph of the dispersion before exfoliation. Fig 1-E, Fig 1-F, and Fig 1-G are the photographs shortly after, 30 days and 4 months after exfoliation respectively.</p

Electrophoretic mobility measurements and estimated zeta potential for water dispersion before exfoliation on the left, dispersion measured right after liquid exfoliation on the middle and, on the right dispersion measured after 30 days of liquid exfoliation.

<p>The number of particles exceeded 1 million on each measurement. The same measurement cell and sample were used for the PSD measurements.</p

FTIR spectrum for MoS₂.

<p>The data for measurements were offset on the vertical axis for clarity.</p

A probability decay equation (Eq 1) was applied to the stability data reported by other authors in the referenced papers and the stability data for the present work.
