The invention discloses an MXene-based solvent-free nano fluid and a preparation method thereof, wherein the preparation method comprises the following steps: the composition comprises the following components: 5-8% of MXene nano particles, 90-95% of flexible organic molecular chains and 3-5% of coupling agent; (II) the preparation method comprises the following steps: s1, using lithium fluoride and hydrochloric acid as an etchant, magnetically stirring a MAX phase serving as a raw material in the etchant, centrifuging, washing with water until the pH value is =7, and freeze-drying to obtain MXene nanosheet powder; s2, dissolving the flexible organic molecular chain in a methanol solution, and then adding coupling agent with equimolar amount. The MXene-based solvent-free nano fluid obtained by the preparation method has excellent physical and chemical properties of MXene nano sheets and flowability of the fluid, can be used as a nano filler to improve the flame retardant property of a flame retardant material, improve the mechanical property of a reinforced polymer-based composite material, improve the barrier property of a coating and the like, and is simple and easy to implement, low in cost and worthy of popularization. |
