Abstract
Introduction. Micro-initiation systems are crucial for the advancement of smart combustible technologies, enabling highly localized and controlled initiation of energetic reactions at the microscale. These systems are essential in applications such as micro-chips, MEMS devices, and smart munitions, and they depend on energetic composite materials (ECMs) that effectively balance performance and safety. Objective of the study. This review examines the relationships between composition and performance in energetic materials (ECMs) used in micro-initiation systems. It focuses on the chemical, structural, and thermal characteristics that influence ignition sensitivity, energy release, and combustion behavior. Key materials—including copper(II) azide, HMX, RDX, CL-20, and TAGN—are evaluated alongside advanced carbon nanomaterials and nanocomposites that enhance safety and performance. Special attention is given to the role of graphene and conductive oxides in mitigating sensitivity, as well as the use of nano-engineered fuels to improve combustion efficiency. Results and Discussion. Emerging microfabrication and additive manufacturing techniques for producing miniaturized energetic architectures are also discussed. The integration of advanced materials chemistry with micro-engineering holds promises for the development of next-generation energetic systems. Conclusions. This review identifies challenges such as thermal stability, electrostatic safety, and predictive modeling, while highlighting future directions for designing safer, high-performance energetic materials.
