Abstract
AbstractThe preparation and characterization of high‐energy density hydrocarbon fuel JP‐10 supramolecular gel propellants are reported. The low‐molecular mass gelator 1,1′,1′′‐((2,4,6‐trioxo‐1,3,5‐triazinane‐1,3,5‐triyl)tris(hexane‐6,1‐diyl))tris(3‐octadecylurea) (HDIT‐18) shows powerful gelation ability for JP‐10, the critical gelator concentration for JP‐10 is as low as 0.0638 wt‐%. The JP‐10 supramolecular gel propellants exhibit high thermal stability. Scanning electron microscopy (SEM) studies reveal that the gelator molecules self‐assemble into 1–3 μm fibers in JP‐10. Rheological studies show the JP‐10 supramolecular gels are thixotropic and shear‐thinning (for a shear rate range from 0.3 to 30 s−1), the dynamic strain sweep test shows that the critical strain percentage of the gel materials is 1 %. The studies reported herein provide a potential fuel material for gel propellants.
