Abstract:
If they could be easily exfoliated, layered materials would become a diverse source
of 2-dimensional crystals whose properties would be useful in applications from
electronics to energy storage. We show that layered compounds such as MoS2, WS2,
MoSe2, MoTe2, TaSe2, NbSe2, NiTe2, BN and Bi2Te3, can be efficiently dispersed in
common solvents and can be deposited as individual flakes or formed into films.
Electron microscopy confirms the material to be exfoliated into individual layers. By
blending with suspensions of other nano-materials or polymer solutions, we can
prepare hybrid dispersions or composites which can be cast into films. We show that
WS2 and MoS2 effectively reinforce polymers, while WS2/carbon nanotube hybrid
films have high conductivity leading to promising thermoelectric properties.
