To improve the safety of HMX, HMX/NH 2 -GO composite was prepared with aqueous ammonia func-
tionalized graphene oxide (NH 2 -GO). The composite was characterized by SEM, Zeta potential, XPS,
Raman spectrum, XRD, HPLC, DSC and BAM sensitivity test. The results indicated that the functionali-
zation with aqueous ammonia can enhance the interaction between GO and HMX, and more efficiently
desensitize the explosive. The optimal impact sensitivity of the HMX/NH 2 -GO composite can be not less
than 40 J, which is also the most insensitivity compared to the previous reports prepared by coating
desensitization with non-energetic desensitized material. Moreover, the potential reason for the
different impact and friction sensitivity was also discussed, which may bring a novel perspective to
achieve the desensitization of energetic material.
