Research Progress in Metal-fluoropolymer Mechanical Activation Energetic Composites

Embarked from the recent development of metal-fluoropolymer mechanical activation energetic composites (MAECs),the energy properties of metal-fluoropolymer were introduced,the energy advantages and release mechanism were analyzed.The typical defects of metal-fluoropolymer were summarized as the low energy release rate caused by the large diffusion distance between two components.The method of adjusting the energy release rate was compared,such as the use of nano aluminum powder,design of the micro device of reaction materials and the mechanical activation treatment.The superiority of mechanical activation was also analyzed.The research status of the mechanical activation process,reaction mechanism,detonation performance and application of MAECs was reviewed.The present status and problems of the research on MAECs of metal-fluorine polymer were evaluated,and the future development trend was also discussed.With 64 references.
