NOVELTY - Graphene toughened two-dimensional high-nitrogen material doped with nitramine oxidant comprises 0.5-1.5 wt.% graphene toughened two-dimensional high-nitrogen material and 98.5-99.5 wt.% nitroamine oxidant, where the graphene toughened two-dimensional high-nitrogen material is a two-dimensional structure formed by graphene oxide, triaminoguanidine nitrate and a 40% glyoxal solution that has a restricted effect on the nitroamine oxidant. USE - Used as graphene toughened two-dimensional high-nitrogen material doped with nitramine oxidant. ADVANTAGE - The material: is stable; has dense ammonium nitrate energetic material; improves the thermal stability and crystal density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene toughened two-dimensional high nitrogen material doped with a nitramine oxidant comprising (i) dispersing graphene oxide GO with an oxygen content of greater than or equal to 45% in an organic solvent, and ultrasonically treating for 60 minutes to obtain a graphene oxide suspension, mixing 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride EDC and N-hydroxysuccinimide NHS deionized water at a temperature of 70-75 degrees C, adding liquid to the dispersion of GO, and placing for 30 minutes to obtain dispersion of GO with activated carboxy groups, under the condition of 70-75 degrees C, adding triaminoguanidine nitrate TAGN to the above mixed solution, reacting for 4 hours to obtain GO-TAG black flocculent precipitate, naturally cooling to room temperature, performing suction filtering and drying, where the mass ratio of EDC and NHS in the deionized water mixture of prefabricated EDC and NHS is 4:3, (ii) dispersing GO-TAG in dimethyl sulfoxide at 70-75 degrees C to obtain GO-TAG dimethyl sulfoxide dispersion, (iii) adding TAGN with a molar ratio of 1:8-1:3 to CL-20 after being fully dissolved, a suspension containing TAGN and GO-TAG is obtained, (iv) adding epsilon -CL-20 powder to the resultant suspension, after CL-20 is completely dissolved, slowly adding 40% glyoxal by dropwise with a molar ratio of 1:1 to 1:1.5 to TAGN solution, reacting for 60-70 minutes, (v) slowly adding deionized water with a volume ratio of 1:1 to dimethyl sulfoxide dropwise into the resultant mixture, placing for 10-15 minutes, rinsing with distilled water at 40-45 degrees C for 4 times, suction filtrating and vacuum drying to obtain graphene oxide-triaminoguanidine nitrate complex GO-TAGP doped CL-20 energetic material, where the doping amount of GO-TAG is 0.5-1.5 wt.%, the mass ratio of GO to EDC in step 1 is 5:1, and the mass ratio of NHS is 20:3, and the mass ratio of TAGN added to the original GO mass ratio is 10:1.
