The present invention relates to the field of coatings on high-energy materials, devices or products that comprise the coated high-energy materials, functional coating materials and methods for producing and using the same. In particular, the present invention relates to energetic materials having initiated release coatings to improve the performance and shelf-life of the devices, products and/or raw materials, suitable for use as energetics or propellants for munitions, rockets, pyrotechnics, flares or other devices or components.

The invention is directed to a propellant charge for guns, to a combination of a propellant charge and a primer, to a firearms cartridge, and to a method for modifying the surface of a propellant charge.

The propellant charge of the invention comprises multiple propellant grains, wherein an exterior part of part of the propellant grains has been subjected to a surface modification treatment comprising the successive steps of suspending propellant grains in water to prepare a slurry, adding an organic solvent to the propellant grains before, after and/or during the preparation of the slurry, mixing the slurry that comprises water and organic solvent for a period of 120 minutes or less, lowering the concentration of organic solvent, removing organic solvent, and drying the propellant grains to remove water;
wherein part of the propellant grains has not been subjected to the surface modification treatment.

An infused solid polymeric fuel for use in a hybrid rocket or as explosive ordnance. An infused solid polymeric fuel can include a porous polymeric body having continuous pores distributed throughout a volume of the polymeric body and connecting to an external surface of the polymeric body. A combustion enhancement agent can be infused into the polymeric body. The combustion enhancement agent can be deposited on interior surfaces of the pores and on the external surface of the polymeric body. The combustion enhancement agent can include a catalyst, an oxidizer, a hypergolic fuel, or a combination.

The invention is directed to a radiation curable energetic composition, to a method of forming a three-dimensional energetic object, to a three-dimensional energetic object, and to uses of the radiation curable energetic composition. The radiation curable energetic composition of the invention comprises (a) one or more polymerisable components, (b) one or more polymerisation initiators, and (c) one or more energetic components.

The invention relates to an energy-releasing composite material comprising at least one nanoporous material and at least one inorganic oxidant, characterised in that said nanoporous material is a nanoporous carbon material.
