Study on a Two-dimensional nanomaterial reinforced wormlike micellar system

Abstract A two-dimensional nanomaterial reinforced wormlike micellar system was constructed by wormlike micelles composed of sodium oleate (NaOA) with potassium chloride (KCl) and two-dimensional lamellar nano-molybdenum disulfide (nano-MoS2). The morphology of nano-MoS2 was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Cryogenic transmission electron microscopy (Cryo-TEM) revealed the formation of wormlike micelles. Then, rheological tests show that the viscosity and viscoelasticity of the system can be enhanced with a certain concentration of nano-MoS2. In addition, environmental scanning electron microscopy (ESEM) demonstrated the adsorption and combination of nano-MoS2 with wormlike micelles can form a tighter three-dimensional network structure. Finally, the strengthening effect of nano-MoS2 on worm-like micelles was confirmed by rheological parameters. The interaction between nano-MoS2 and wormlike micelles was elucidated and the mechanism of nano-MoS2 reinforcing wormlike micelles was proposed. Through this research, we hope to broaden the range of applications of two-dimensional nanomaterials.
