Inspired by the better desensitizing effect introduced by enhanced interaction, ammonium formate (Am) was utilized to modify graphene oxide (GO) and the functional graphene oxide (Am−GO) was obtained in this work, which was endowed with more amino groups and completely positive charge. Due to the modification and corresponding enhanced interaction, the impact sensitivity and friction sensitivity of HMX/Am−GO can be desensitized to 40 J and 192 N, respectively. To further desensitize the friction sensitivity, graphite (G) was utilized to replace part of Am−GO. And HMX/Am−GO/G was endowed with 40 J and 360 N of impact sensitivity and friction sensitivity respectively, which is the best desensitizing effect of HMX to our best knowledge. Furthermore, CL-20 and DNTF were coated by the same coating, which also can be desensitized with the best effect. In addition, because the coating process is performed in water at room temperature, this desensitization is environment-friendly and benefit for the large scale of production. This work demonstrates the improved desensitizing effect with enhanced interaction and provides a potential general applicable method for desensitization.

高能材料的相互作用增强涂层：一种普遍适用的脱敏方法
受增强的相互作用带来的更好的脱敏效果的启发，利用甲酸铵（Am）对氧化石墨烯（GO）进行了改性，得到了功能性氧化石墨烯（Am-GO），它赋予了更多的氨基和完全正电荷。由于改性和相应增强的相互作用，HMX/Am-GO 的冲击敏感性和摩擦敏感性可以分别降低到 40 J 和 192 N。为了进一步降低摩擦敏感性，石墨（G）被用来代替部分Am-GO。而 HMX/Am−GO/G 分别赋予了 40 J 和 360 N 的冲击敏感性和摩擦敏感性，据我们所知，这是 HMX 的最佳脱敏效果。此外，CL-20和DNTF涂有相同的涂层，脱敏效果也最好。此外，由于包衣过程是在室温下在水中进行的，这种脱敏方式对环境友好，有利于大规模生产。这项工作通过增强的相互作用证明了改进的脱敏效果，并提供了一种潜在的通用脱敏方法。
