Abstract
A new approach to formulating pyrotechnic materials is presented whereby constituent ingredients are bound together in a solid-state lattice in the form of a Metal-Organic Framework. This reduces the batch inconsistencies arising from the traditional approach of combining powders by ensuring the key ingredients are ‘mixed’ in stoichiometric quantities and are in intimate contact. Further benefits for the application of these types of material are increased safety levels as well as simpler logistics, storage and manufacture. A systematic series of new frameworks comprising fuel and oxidiser agents (group 1 and 2 metal nodes and terephthalic acid derivatives as linkers) has been synthesised and structurally characterised. These new materials have been assessed for pyrotechnic effect by calorimetry and burn tests. Results indicate that these materials exhibit the desired properties of a pyrotechnic mate-rial and that the effect can be correlated to the di-mensionality of the structure.
