Controlled Synthesis of Tetrazole Energetic Polymers with Tailored Macroscopic Properties
Abstract
The proposed research aims to demonstrate that high-performance energetic polymers can be designed at the molecular level to meet specific bulk properties using modular, safe and scalable flow technology. (1) Apply theory (DFT calculations) as guidance in the synthesis of substituted tetrazoles and in the tailoring of their energetic properties: substituent effects on ÒClickÓ regiochemistry and on thermal decomposition of substituted tetrazoles (2) Develop synthetic protocols from batch to flow for (a) controlling the molecular weight and polydispersity in the formation of poly (epichlorhydrin) and related polymers, (b) controlling the regiochemistry of tetrazole formation via ÒClickÓ chemistry and metal-catalyzed ÒClickÓ chemistry, and (c) varying substituents (nitrogen-rich or oxygen-rich substituents) on the tetrazole ring (3) Apply 1H and 13C NMR spectroscopy, mass spectroscopy, and thermal analytical methods to confirm the structures and thermal properties of synthesized materials. (4) Transition from Batch to Continuous Flow processes for the safe manufacture of energetic materials leveraging principles of green chemistry and engineering. (5) Extend experimental results to other energetic polymeric systems
