Polynigrogen Energetic Materials

Journal of the Korea Institute of Military Science and Technology, 2016
ABSTRACT Current research trends of prediction of possible structures, synthesis and explosive characteristics of polynitrogen molecules(PNs) are reviewed. Theoretically PNs are composed only of nitrogen atoms, in which N-N bonds are either single or double bonds, and thus when these molecules decompose, release of enormous energy is accompanied.
