Synthesis Of Two-dimensional Materials (MoS₂ And Mxene) And Its Application In The Field Of Electromagnetic Rheology

In this article,we summarized the development history,preparation methods and properties of two-dimensional materials?MoS₂ and MXenes?in recent years and their related research progress in the field of electro-magnetic rheology.We prepared related nanocomposites by hydrothermal methods and Pickering emulsion polymerization to apply them in the field of electro-magnetic rheology.Firstly,we prepared Fe₃O₄ by hydrothermal method,and combined it with MoS₂ nanosheets to further modify the TiO₂ by hydrolysis to prepare magnetic nanocomposites with unique rheological behavior.Secondly,we prepared oxidized MXenes by hydrothermal oxidation,and then synthesized bayberry-like polystyrene/TiO₂/C spheres by Pickering emulsion polymerization,and applied them to the field of electrorheological fields.The details are as follows:Intelligent materials have been attracting enormous attention in recent decades because of their significant features,which are sensitive to external stimuli such as magnetic or electric fields,temperature,electrolyte concentration,pH,and light.We focus on the recent research progress in the field of electro-magnetic rheology of MoS₂ and MXenes,and prospect its potential applications and the field of electro-magnetic rheology.Then,we reported a facile way to fabricate core–shell structured Fe₃O₄@MoS₂@TiO₂nanoparticles.As the core material,Fe₃O₄ nanoparticles with a diameter of 400 nm were prepared by ahydrothermal method,while in the shell part,MoS₂ was synthesized through the hydrothermal method and TiO₂ nanoparticles were decorated on the MoS2 nanosheets through a hydrolysis method,sequentially.To reveal the unique rheological behaviors of the resultant particles,the coefficient of friction?COF?of the Fe₃O₄@MoS₂@TiO₂ based suspension was examined using a UMT-3micro-tribometer.The relationship between unique rheological behaviors and the hierarchical structure was discussed in this work.The polystyrene?PS?/TiO₂/C particles were polymerized by Pickering emulsion stabilized using the organic solid stabilizer-TiO₂/C hybrid derived from Ti₃C₂T_x MXenes.The TiO₂/C demonstrates a hydrophilic surface terminated by oxygen-containing groups,which is suitable for Pickering polymerization.On the other hand,TiO₂ is widely used as a backbone material in a hybrid structure,and it is considered as a good candidate for ER materials due to its high dielectric constant and suitable dielectric relaxation.We extend the polystyrene?PS?/TiO₂/C particle to develop an interesting electro-responsive material to develop an interesting electro-responsive material.
