摘　　要：为了制备结构均匀且热性能优异的纳米复合含能材料,采用脱氧核糖核酸(DNA)自组装法在室温和水相中制备了CuO/Al纳米复合含能材料。采用红外光谱(FT?IR)、动态光散射(DLS)、透射电镜(TEM)、扫描电镜(SEM)以及差示扫描量热仪(DSC)表征了纳米复合含能材料的结构及热反应性能。结果表明,通过DNA自组装法成功制备了一种微观结构更均匀的CuO/Al纳米复合含能材料;DNA自组装样品与同配比物理共混样品相比具有更高的反应热,且当φ=1.6时,自组装样品反应热达到1520 J?g^(-1),比同配比物理共混样品(999 J?g^(-1))提高52.15%。To prepare nanocomposite energetic materials with homogeneous structure and excellent thermal properties,CuO/Al nanocomposite energetic materials were prepared by deoxyribonucleic acid(DNA)self-assembly method at room temperature and in water phase.The structures and thermal reaction properties of the nanocomposite energetic materials were characterized by Fourier transform infrared(FT-IR)spectroscopy,dynamic light scattering(DLS),transmission electron microscope(TEM),scanning electron microscope(SEM)and differential scanning calorimeter(DSC).Results show that CuO/Al nanocomposite energetic materials with more homogeneous structure are successfully prepared by DNA self-assembly.The reaction heat of DNA self-assembled CuO/Al nanocomposites is higher than that of physically mixed samples with the same proportion and atφ=1.6,the reaction heat of DNA self-assembled CuO/Al nanocomposites reaches 1520 J·g-1,which is 52.15%higher than that of the physically mixed samples(999 J·g-1).
