The invention discloses a preparation method of a cellulose nanocrystal synergistic induction light limiting film. The preparation method specifically comprises the following steps of: 1, synthesizing an MXene aqueous dispersion solution; 2, preparing cellulose nanocrystals; and 3, preparing the MXene cellulose nanocrystal optical limiting film according to results obtained in the step 1 and the step 2. The invention provides a method for preparing an MXene material. The MXene material and cellulose nanocrystals (CNC) with nonlinear scattering are compounded to prepare a novel solid film material. 本发明公开了一种纤维素纳米晶协同诱导光限幅薄膜的制备方法，具体包括如下过程：步骤1，合成MXene水分散溶液；步骤2，制备纤维素纳米晶；步骤3，根据步骤1和步骤2所得结果制备MXene纤维素纳米晶光限幅薄膜。本发明提供了制备MXene材料的方法，将MXene材料与具有非线性散射的纤维素纳米晶(CNC)复合制备成一种新型的固体膜材料。
