In this work, graphene oxide-doped lead-containing metal-organic framework (BTC−Pb/GO) and polyvinyl alcohol were used as raw materials to prepare spherical or cylindrical lead azide composites by freeze-drying, carbonization, and in-situ azide steps. Nanoscale lead azide is uniformly distributed on the graphene-doped porous carbon framework. Detailed characterization and testing show that LA/C/rGO exhibits excellent electrostatic sensitivity (1.94 J) and flame sensitivity (40 cm) due to the excellent electrical and thermal conductivity of porous carbon and graphene, which are superior to most of the previously reported modified lead azide.

具有优异点火能力的石墨烯掺杂多孔碳基体包覆高能叠氮化铅纳米粒子的成型制备

本工作以氧化石墨烯掺杂的含铅金属有机骨架（BTC-Pb/GO）和聚乙烯醇为原料，通过冷冻干燥、碳化、原位叠氮化制备球形或圆柱形叠氮化铅复合材料。脚步。纳米级叠氮化铅均匀分布在石墨烯掺杂的多孔碳骨架上。详细的表征和测试表明，由于多孔碳和石墨烯的优异导电性和导热性，LA/C/rGO 表现出优异的静电敏感性（1.94 J）和火焰敏感性（40 cm），优于大多数先前报道的改性叠氮化铅。
