Abstract

The invention provides a deuterated supramolecular polymer, belonging to the technical field of supramolecular polymers. The deuterated supramolecular polymer is a bifunctional monomer with a deuterated polymer as a spacer obtained after ring-opening metathesis polymerization of a deuterated cycloalkene, through quadruple hydrogen bonds or metal coordination bonds. Quadruple hydrogen bonded deuterated supramolecular polymers or metal coordination deuterated supramolecular polymers formed by non-covalent interactions. The invention also provides a preparation method of the deuterated supramolecular polymer. The main chain of the deuterated supramolecular polymer of the present invention is connected to each other through non-covalent interaction, and has the advantages of self-repair and good processing performance. The preparation source of the deuterated supramolecular polymer of the present invention is simple, the process flow is simple, and the preparation of the deuterated supramolecular polymer with a controllable ratio of unsaturated carbon to saturated carbon can be realized by adjusting the type and molar ratio of deuterated cycloalkene , combined with hydrogen isotope addition reactions can adjust the ratio of hydrogen isotopes in the saturated product.

Description

technical field [0001] The invention belongs to the technical field of supramolecular polymers, in particular to a deuterated supramolecular polymer and a preparation method thereof. Background technique [0002] Inertial confinement fusion technology (ICF) is currently one of the most promising ways to realize controllable fusion power generation and solve the energy crisis. It is necessary to use materials with high atomic density of deuterium and tritium as the ICF target fuel. On the one hand, deuterated polymers can be used as target pellets to fill thermonuclear fuel (such as deuterium-tritium ice); on the other hand, there are many problems in the traditional low-temperature frozen deuterium-tritium target fuel, including the use of cryogenic refrigeration systems, the preparation of target pellets, and the packaging of deuterium-tritium , the homogenization and stratification of deuterium-tritium ice, etc., have brought great challenges to the engineering application...
