An opportunity is available to undertake a fully-funded PhD in the synthesis of energetic materials. The project, in collaboration with AWE, will explore novel materials and methods with the objective of developing new tools for the formulation of explosives. Read more Read less

Aim

Plasticisers are commonly added to explosive formulations to improve the mechanical properties and safety profile of the product. Energetic plasticisers are of particular interest due to the increase in performance available when compared with inert alternatives. A number of plasticisers remain in use due to historical reasons, despite problems such as hazardous production processes, poor performance, toxicity, or instability. These considerations lead to an urgent need for both improved production routes and alternative plasticisers.

Several in-service formulations contain a plasticiser which suffers from many of the drawbacks listed above. It is manufactured using batch nitration methodology under forcing conditions with a large inventory of material. The synthesis of this material using more modern flow chemistry approaches is therefore of interest to reduce the level of process risk and improve product quality.  Whilst this material is required for current formulations, its high toxicity (currently on the REACH list), migratory propensity, low oxygen balance and potential instability make it a key candidate for replacement in future formulations. This project will look at both alternative synthesis methods for the plasticiser as well as alternative known and novel materials for its direct replacement.

The project will consist of the development of scalable flow chemistry routes to both known energetic plasticisers and novel plasticisers for explosive formulations. In addition to the synthetic research carried out, plasticisers produced during the project will be characterised and evaluated for their suitability as additives. This will include assessment of their energetic output, ageing and migration studies, and the hazard properties and performance of binder formulations.

While applicants are required to possess a sound understanding of synthetic chemistry and strong practical laboratory skills, training in equipment use and the synthesis and handling of energetic materials will be provided. It is expected that the real-world applicability of the topic, coupled with the freedom to investigate a variety of molecular targets, will afford opportunities to publish results in high-impact journals and present at industrial and academic conferences.
