摘要

现代高能材料（EMs），如纳米热敏剂和 NSTEX（纳米结构热敏剂和爆炸物）成分正吸引着越来越多的研究兴趣。在这项工作中，我们展示了对掺杂硝酸纤维素（NC）和 5-硝基-1,2-二氢-3H-1,2,4-三嗪-3-酮（NTO）的新型 Ti/CuO 纳米热敏剂体系性能的研究结果。在安全参数方面，对测试系统的摩擦力（40->360 N）、冲击力（40->50 J）和激光辐照灵敏度进行了测定，结果表明该系统具有可调特性。还测量了燃烧速度（高达 735 米/秒）、密闭容器中燃烧的压力参数、推力参数和露天燃烧行为。此外，为了深入研究 NTO 对燃烧机理的影响，还进行了 SEM、DSC/TG 和 XRD 测试。所得结果表明，Ti/CuO/NC/NTO 系统在未来的应用中大有可为。

Novel NSTEX System Based on Ti/CuO/NC Nanothermite Doped with NTO

Modern energetic materials (EMs), e.g., nanothermite and NSTEX (Nanostructured Thermites and Explosive) compositions are attracting increasing research interest. In this work, we present the results of our investigation on the properties of a novel Ti/CuO nanothermite system doped with cellulose nitrate (NC) and 5-Nitro-1,2-dihydro-3H-1,2,4-triazin-3-one (NTO). In terms of safety parameters, the friction 40–>360 N), impact (40–>50 J) and laser irradiation sensitivity were determined for tested systems, which indicated tunable properties. The combustion velocity (up to 735 m/s), pressure parameters for combustion in closed vessel, thrust parameters and open-air combustion behaviour were measured. Moreover, in order to deeply study the impact of NTO on the combustion mechanism, the SEM, DSC/TG and XRD tests were performed. The obtained results indicate that the Ti/CuO/NC/NTO system is extremely promising for future applications.
