NOVELTY - Preparing graphene oxide/glycidyl azide polymer-energetic thermoplastic elastomer composite comprises (a) adding graphene oxide to tetrahydrofuran, and ultrasonically dispersing to obtain graphene oxide dispersion, (b) adding glycidyl azide polymer-energetic thermoplastic elastomer to tetrahydrofuran, stirring, dissolving glycidyl azide polymer-energetic thermoplastic elastomer completely to obtain mixed solution of glycidyl azide polymer-energetic thermoplastic elastomer and tetrahydrofuran, and (c) adding graphene oxide dispersion into glycidyl azide polymer-energetic thermoplastic elastomer and tetrahydrofuran mixed solution, stirring the system uniformly, allowing to stand, and drying to obtain graphene oxide/polyglycidyl azide-based energetic thermoplastic elastomer composite. USE - The method is useful for preparing graphene oxide/glycidyl azide polymer-energetic thermoplastic elastomer composite. ADVANTAGE - The method: can improve the thermal stability of the original glycidyl azide polymer-energetic thermoplastic elastomer; can delay thermal decomposition temperature by 1-4.1 degrees C; can reduce the glass transition temperature of the original glycidyl azide polymer-energetic thermoplastic elastomer; can reduce the temperature range of 1.3-3.5 degrees C; and is easy and economical. DETAILED DESCRIPTION - Preparing graphene oxide/glycidyl azide polymer-energetic thermoplastic elastomer composite comprises (a) adding graphene oxide to tetrahydrofuran, and ultrasonically dispersing at 20-35 degrees C for 1-2 hours, where the dosage ratio of graphene oxide and tetrahydrofuran is 10-60 mg: 20-150 g to obtain graphene oxide dispersion, (b) adding glycidyl azide polymer-energetic thermoplastic elastomer to tetrahydrofuran, stirring at 20-35 degrees C for 1-2 hours, dissolving glycidyl azide polymer-energetic thermoplastic elastomer completely to obtain mixed solution of glycidyl azide polymer-energetic thermoplastic elastomer and tetrahydrofuran, where the dosage ratio of glycidyl azide polymer-energetic thermoplastic elastomer to tetrahydrofuran is 4-6 g: 100-200g, and (c) adding graphene oxide dispersion into glycidyl azide polymer-energetic thermoplastic elastomer and tetrahydrofuran mixed solution, stirring the system at 20-40 degrees C for 0.5-1 hour uniformly, allowing to stand at room temperature for 1-2 weeks, and drying at 30-40 degrees C for 2-4 hours to obtain graphene oxide/polyglycidyl azide-based energetic thermoplastic elastomer composite.
