主　　题：HMX GO Ammonia Surface coating technology 

摘      要：To improve the safety of HMX,HMX/NH_(2)-GO composite was prepared with aqueous ammonia functionalized graphene oxide(NH_(2)-GO).The composite was characterized by SEM,Zeta potential,XPS,Raman spectrum,XRD,HPLC,DSC and BAM sensitivity *** results indicated that the functionalization with aqueous ammonia can enhance the interaction between GO and HMX,and more efficiently desensitize 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 ***,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.
