In recent years, plant polyphenols have emerged as promising, eco-friendly desensitizers for energetic materials. By employing a bionic interface design, we successfully constructed core–shell structured Cyclotetramethylene tetranitroamine (HMX)@polyphenol composites, wherein plant polyphenols form a continuous protective coating. This coating effectively shields the energetic core from external stimuli, leading to a significant improvement in safety. Specifically, the impact sensitivity of the composite was reduced by 1.92 times compared to that of pure HMX. This work successfully integrates the advantages of natural polyphenols with advanced material design, demonstrating substantial potential for developing safer energetic materials.
