亚稳态分子间复合物(metastable intermolecular composite,MIC)由于具有超高反应燃烧速率及能量释放速率、高体积能量密度、低扩散距离和绿色环保等优点,在微型含能器件、火箭推进剂和绿色火工药剂等军用领域展现了很好的应用潜力。其反应机制与传统的含能材料不同,且具有超高速反应的瞬时性及复杂性,对其反应机理仍然缺乏清晰的认识,这限制了其应用研究的进展。本文对近年来亚稳态分子间复合物的反应机理研究进行综述,重点讨论具有代表性的“金属-氧翻转机理”和“预点火-熔结机理”。对于MIC材料的反应机理研究,本文主要从实验研究、理论模型研究和数值模拟研究三个方面进行分析。改性MIC材料是对材料性能进行调控的重要手段,是目前及未来的重要发展趋势之一,在论文最后对其反应机理做了重点叙述。通过对当前研究现状的归纳与分析,给出了当前的重要研究成果以及研究中出现的问题,并对未来的研究发展趋势进行了展望。
Metastable intermolecular composite (MIC) has been widely used in micro energy devices, rocket propellants and micro-energy devices due to its high reaction rate and energy release rate, high volume energy density, low diffusion distance and environmental protection. Green Firework Pharmacy and other military areas show a good potential for application. The reaction mechanism is different from the traditional energetic materials, and has the instantaneous and complexity of ultra-high-speed reaction, and its reaction mechanism is still lack of clear understanding, which limits its application research progress. This review summarizes the reaction mechanism of metastable intermolecular complexes in recent years, and focuses on the representative “metal-oxygen turnover mechanism ” and “pre-ignition - sintering mechanism ”. For the study of the reaction mechanism of MIC material, this paper mainly analyzes from three aspects: experimental study, theoretical model and numerical simulation. Modified MIC material is an important means of material properties regulation and control, is the current and future one of the important trends in the development of the reaction mechanism at the end of the paper made a keynote. Through summarizing and analyzing the current research status, the current important research results and the problems in the research are given, and the future research trends are prospected.
