Embodiment 1
[0043] The preparation method of MXene-based terahertz wave broadband super-absorbing foam with different apertures provided in this example includes the following steps:
[0044] Step 1: Mix hydrochloric acid, hydrofluoric acid and deionized water evenly to obtain 63mL etching solution, wherein the volume ratio of hydrochloric acid, hydrofluoric acid and deionized water is 4:1:2; then, 3g Ti 3 AlC 2 The powder was slowly added to the etching solution, stirred at room temperature for 24 hours, and the Ti was selectively etched away. 3 AlC 2 Al layer in MAX phase, resulting in Ti 3 C 2 T x MXene acid solution;
[0045] Step 2: Ti obtained in Step 1 3 C 2 T x Add deionized water to the acidic solution of MXene for centrifugation and washing for several times until the pH value of the supernatant is 6, then filter and separate to obtain multilayer Ti 3 C 2 T x MXene precipitates; then, the resulting multilayer Ti 3 C 2 T x The MXene precipitate was dispersed in...
