Nanomaterials for applications within energetic materials (EM) are interesting since the particle size affects the properties of a material. There are today studies which indicate that the impact sensitivity could decrease with decreasing particle size, however there is a need for more studies and comprehensive statistic investigation in order to establish that the sensitivity is really decreasing with decreasing particle size. A benefit of using nano-sized EMs would thereby be to make sensitive materials such as CL-20 less sensitive, if the sensitivity is decreasing with decreasing particle size. Energetic nanomaterials are thereby interesting from an insensitive munitions perspective. There are today a number of studies where nano-sized EMs are produced by a number of different methods and then characterized by size, shape and impact sensitivity. The area has however, even if research has been going on for about 10-20 years not had any by the authors known commercial breakthrough, except for nano-sized aluminium. There are few studies where composite materials or complete formulations of energetic nanomaterials are produced. This could indicate the problem of producing a formulation containing nano-sized EMs. Nanoparticles do affect the viscosity and processability of the formulation. Another question within the area is the upscalability of the methods which have been applied. FOI should keep contact, have a dialog and possibly collaborate with research facilities already established within the field. FOI should in addition follow the literature and development of the field.
