Cations in ionic liquid form a cation layer around spherical tungsten disulfide particles to prevent their contact. In this way, ionic liquid can effectively disperse spherical tungsten disulfide in lubricating oil.

Nanocomposite of polypyrrole and tungsten disulfide can be prepared by inserting polypyrrole into tungsten disulfide layers. Usually, the peeling-recomposition technology and monomer intercalation method are applied in this simple preparation method.

Composite of tungsten disulfide and graphene, with two-dimensional structure, has high catalytic activity and excellent electro-catalytic properties. It has broad application prospects in the field of full cell and is regarded as a material to replace the traditional electrocatalyst.

Nanocomposite of polyether and tungsten disulfide can be prepared by inserting polyether polymer into tungsten disulfide layers and the peeling-recomposition technology is used in the preparation process. As for the peeling-recomposition technology, it involves three steps: monolayer peeling, polymer solution direct intercalation and recomposition.
