This study aims to enhance the mechanical properties of energetic polymer bonded explosives (PBXs) by modifying 1,3,5-triamino-2,4,6-trintrobenzene (TATB) crystals—a typical energetic material—using 2-ureido-41H-6-methyl-pyrimidinone (UPy) derivatives with strong hydrogen-bonding interactions. Specifically, strongly adhesive polydopamine (PDA) was employed to graft UPy-functionalized molecules with isocyanate groups (–NCO) and hydroxyl groups (–OH). Scanning electron microscopy (SEM) images indicate that TATB crystals became rougher after being coated with PDA, while the introduction of UPy did not affect the surface morphology. The presence of urethane bond peaks in the samples indicates that UPy-NCO was successfully grafted onto the PDA. UPy is essentially nonpolar and is prone to bind with binders, having the potential to improve the creep resistance of PBXs. Due to the strong interfacial enhancement by UPy and PDA, the tensile strength and compressive strength of the sample grafted with 1 wt% UPy significantly increased by 35.6 % and 26.5 %, respectively. Theoretical calculations indicate interfacial enhancement by UPy introduction, where the strong hydrogen bonding may produce a positive impact. The successful introduction of UPy modified the nature of TATB and improved its interfacial strength, finally enhancing the mechanical properties of the PBXs. The conditions for the grafting reaction in this study are mild and universal and thus can be applied to other compositions.</div>","PeriodicalId":34595,"journal":{"name":"Energetic Materials Frontiers","volume":"5 2","pages":"Pages 121-130"},"PeriodicalIF":3.3,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666647224000344/pdfft?md5=9a78e52b225fdd71ff77dddf673d40df&pid=1-s2.0-S2666647224000344-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141136707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ionic liquids (ILs) and hydrogen peroxide have demonstrated their feasibility as a green fuel and an oxidizer, respectively. However, the realisation of effective auto-ignition is the key problem. In this study, a new strategy to trigger the auto-ignition of ILs fuels with hydrogen peroxide by using a unique copper-containing liquid as the promoter is developed. The copper-containing promoter is designed such that its cationic structure is similar to that of the ILs fuels. Based on the principle of “like dissolves like,” the fuel and promoter can be miscible at any ratio to eventually form a catalytic fuel. In addition, the physicochemical properties (e.g. density, viscosity and decomposition temperature) and performance parameters (e.g. ignition delay time and specific impulse) of the as-prepared catalytic fuel are completely characterised. Owing to their excellent hypergolic performance with a short ignition delay time of 16 ms, in combination with the advantages of simple preparation, perfect solubility and green characteristics, the catalytic fuel–oxidizer pair demonstrates promise as bipropellants for rocket applications.</div>","PeriodicalId":34595,"journal":{"name":"Energetic Materials Frontiers","volume":"5 1","pages":"Pages 41-46"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666647224000071/pdfft?md5=6f75e4c45e7f13be8f845719334cce58&pid=1-s2.0-S2666647224000071-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139872378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
