Polymeric, shock-insensitive, tunable explosives with long shelf-life
Central Michigan University
posted on 06/22/2009
A penta-nitrated polymeric family has exceptionally high overall energy or power of detonation. The explosive materials can be “tuned” by varying the length of the aliphatic alkyl chains.
Advantages
These compounds belong to a group of explosives, which are insensitive to accidental shocks including thermal, electrical, and mechanical ones.
The explosive power can be designed or tuned by changing the number of nitro groups present in each repeat unit.
Detailed Description
The density of the polymer was measured using a picnometer (d = 1.625 g/cc), and the heat of combustion was determined experimentally using a bomb calorimeter (-7,535.8 kJ / mol). Using these two values and the Kamlet-Jacob equations, the detonation velocity is calculated as 10.5 km / s, and the detonation pressure is 4.72 * 10^10 Pa
