Title The preparation of MoS2 / PVA nanocomposites and their performance
Abstract
Compared to ordinary MoS2， MoS2 size in the nanometer level in the specific surface
area, catalytic properties, reaction activity and adsorption performance is
significantly improved. Showed a good catalytic, lubrication, photoelectric
performance and the performance of the composite of all kinds of composites
also has the obvious rise, thus has applied in many fields.In this paper,MoS2/PVA
nanocomposites by MoS2 nanosheets dispersion was achieved via the
rapidhydrolysis of LixMoS2 mixed directly with polyvinyl alcohol（PVA）aqueous
solution. Then using Raman spectroscopy, scanning electron microscope (SEM),
transmission electron microscopy (TEM), X-ray diffraction (XRD) and ultraviolet
visible light absorption method for MoS2 and MoS2 / PVA composite materials were
characterized and analyzed. The results show that Successful fabricate the MoS2
nanosheets,the thickness about 25 nm; MoS2 nanosheets evenly dispersed in the
PVA; MoS2/PVA nanocomposites for the absorption of visible light is not strong,
the area of absorption in the UV area.
