Embodiment 1
[0027] A nanocomposite energetic material composed of CL-20 and a three-dimensional ordered macroporous carbon framework with a pore diameter of 300nm. The SEM photo of the three-dimensional ordered macroporous carbon framework material with a pore diameter of 300nm and a content of CL-20 is 33.3%. figure 1 shown.
[0028] Take 0.05g of CL-20 at room temperature and dissolve it in 4.0g of acetone under magnetic stirring at a speed of 300 rpm, and stir until CL-20 is completely dissolved. Take 0.1 g of a three-dimensional ordered macroporous carbon framework material with a pore diameter of 300 nm and add it to the solution, and stir for 5 minutes under magnetic stirring at a speed of 100 rpm until uniformly mixed. The mixture was left standing at room temperature, and after all the solvent evaporated, a black-green solid was obtained. It was further dried in air at 65°C to obtain a nano energetic composite material with a CL-20 content of 33.3%. Its XRD spectrum is shown in ...

[0030] A nanocomposite energetic material composed of CL-20 and a three-dimensional ordered macroporous carbon framework with a pore diameter of 300nm. The TEM photo of the three-dimensional ordered macroporous carbon framework material with a pore diameter of 300nm and a CL-20 content of 52.4% is as follows figure 2 shown.
[0031] At room temperature, 0.11 g of CL-20 was dissolved in 4.0 g of acetone under magnetic stirring at a speed of 300 rpm, and stirred until CL-20 was completely dissolved. Take 0.1 g of a three-dimensional ordered macroporous carbon framework material with a pore diameter of 300 nm and add it to the solution, and stir for 5 minutes under magnetic stirring at a speed of 100 rpm until uniformly mixed. The mixture was left standing at room temperature, and after all the solvent evaporated, a black-green solid was obtained. It was further dried in air at 65°C to obtain a nano energetic composite material with a CL-20 content of 52.4%. Its XRD spectrum i...
Embodiment 3
[0033] A nanocomposite energetic material composed of CL-20 and a three-dimensional ordered macroporous carbon framework with a pore size of 300nm, its SEM photo is as follows image 3 As shown, the CL-20 content is 62.9%.
[0034]Take 0.17g of CL-20 at room temperature and dissolve it in 4.0g of acetone under magnetic stirring at 300 rpm, and stir until CL-20 is completely dissolved. Take 0.1 g of a three-dimensional ordered macroporous carbon framework material with a pore diameter of 300 nm and add it to the solution, and stir for 5 minutes under magnetic stirring at a speed of 100 rpm until uniformly mixed. The mixture was left standing at room temperature, and after all the solvent evaporated, a black-green solid was obtained. It was further dried in air at 65°C to obtain a nano energetic composite material with a CL-20 content of 62.9%. Its XRD spectrum is shown in Figure 4 shown. Figure 5 DSC analysis shows that the initial decomposition temperature of the nano en...
