Thin layer tungsten disulfide powder(Send original solution)

Product Overview
Thin Layer WS₂ Powder consists of tungsten disulfide nanosheets with a well-defined layered structure similar to graphene. This transition metal dichalcogenide features a unique “sandwich” configuration where tungsten atoms are covalently bonded between two sulfur layers, with multiple layers stacked via weak van der Waals forces. We synthesize this material through a lithium intercalation process: using n-butyllithium to insert lithium ions between WS₂ layers, forming an intercalation compound that expands in solvent and is exfoliated via ultrasonication before freeze-drying. The resulting powder exhibits a 1T-2H hybrid crystal structure with approximately 60% 1T phase content (batch-dependent).
