Abstract
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.
Claims29
Composite energetic material comprising at least one nanoporous material and at least one inorganic oxidiser, characterised in that said nanoporous material is a nanoporous carbonaceous material, said composite energetic material has a decomposition initiation temperature on a thermogram obtained by differential scanning calorimetry of less than 5° C./minute in a closed crucible (DSC peak start temperature) preferably from 50° C. to 200° C., more preferably from 100° C. to 150° C., relative to the decomposition initiation temperature on the DSC thermogram of the inorganic oxidiser, and has at least 30% of the porosity occupied by said inorganic oxidiser, and at most 90% of the porosity occupied by said inorganic oxidiser, said energetic material having an impact sensitivity of at least 2 J,
- wherein said nanoporous carbonaceous material comprises a network of interconnected pores in a three-dimensional arrangement of pores which extend through the volume of said nanoporous carbonaceous material,
- said nanoporous carbonaceous material comprises micropores with a pore size not exceeding 2 nm, mesopores with an intermediate size of between 2 and 50 nm and macropores with a pore size of greater than 50 nm and less than 100 nm;
- and
- said nanoporous carbonaceous material having a volume of micropores of between 0.1 cm3/g and 1.0 cm3/g and a volume of mesopores of between 0.05 cm3/g and 3.0 cm3/g, calculated based on the pore size distribution modelled by 2D-NLDFT-HS (non-linear DFT) or QSDFT (quench-state DFT) applied to nitrogen adsorption isotherms at 77.4K.
