Zusammenfassung:Disclosed are a high-strength flame-retardant MXene/phosphorylated cellulose fibril composite film and a preparation method therefor, belonging to the field of high polymer materials. Phosphorylated cellulose nanofibrils are uniformly dispersed in an aqueous solution, chitosan and MXene are added, and the mixture is mixed uniformly and dried to obtain a composite film. The present invention utilizes MXene and introduces chitosan to achieve the enhancement of flame retardance and thermal stability of the phosphorylated cellulose nanofibrils. Meanwhile, the interaction between MXene and the phosphorylated cellulose fibrils can be enhanced, and the mechanical properties of the composite film can be improved in combination with the nano-enhancement effect of MXene. The phosphorylated cellulose fibril film synergistically modified by MXene and chitosan and prepared in the present invention not only has excellent flame retardance, but also has greatly improved mechanical properties. The composite film can be used a
