Abstract

The invention relates to a triureido organic gel factor, a preparation method and application thereof. The triureido organic gel factor takes hexamethylene diisocyanate trimer and saturated primary amine as the raw materials for one-step reaction preparation. By heating dissolving and cooling gelling of the triureido organic gel factor, the high-density hydrocarbon fuel exo-tetrahydrodicyclopentadiene can be prepared into an organic gel material. The triureido organic gel factor synthesis steps are simple, the conditions are mild, and no special synthesis device is needed. The triureido organic gel factor can make the high-density hydrocarbon fuel exo-tetrahydrodicyclopentadiene into an organic gel material, the gel material has a simple preparation process, can realize mass preparation, and has very good application prospects in high-energy gel propulsion systems.

Description

technical field [0001] The invention belongs to the technical field of supramolecular chemistry, and in particular relates to a synthesis and preparation method of a novel triurea-based organic gel factor. Background technique [0002] Under the drive of intermolecular hydrogen bonds, π⁃π stacking, hydrophilic-hydrophobic interactions, van der Waals forces and other non-covalent weak interactions, small organic molecules self-assemble to form a physical gel with a three-dimensional network structure, which is called a supramolecular gel. . Gelation factors containing urea groups have become particularly effective hydrogen-bond assembly units in the assembly of supramolecular gels due to their strong hydrogen-bond association ability and tunable diversity of interactions with anions, metal ions, and halogen compounds. Polyurea-based gelling factor, compared with diurea-based gelling factor, its increased hydrogen bond assembly unit makes it have stronger hydrogen bond formin...
