Aqueous Dispersion of One-Dimensional van der Waals Material Mo 6 S 3 I 6 with the Charge Type of the Hydrophobic Dispersant Tail.

Aqueous dispersion of van der Waals bonded one-dimensional materials Mo 6 S 3 I 6 with hydrophobic surfaces has been studied. The surface charge of the dispersed Mo 6 S 3 I 6 is controlled from negative to positive by the charge type of dispersant tail (anionic, SDS and NaDDBS; cationic, CTAB; nonionic, Poloxamer 407), and through this, it is possible to deposit the dispersed Mo 6 S 3 I 6 in nanosized by electrophoretic deposition at a desired position. When a flexible device was manufactured by transferring Mo 6 S 3 I 6 , it was confirmed that electrical conductivity can be measured in 40% of elongation and more than 1000 times cyclic test.
