Problems solved by technology

[0003] At present, the types of supramolecular interactions discovered are becoming more and more abundant, and there are more and more reports on the dynamic crosslinked polymers formed by supramolecular interactions, mainly focusing on the fact that each dynamic crosslinked polymer contains only one kind of supramolecular interactions. Molecular interaction provides the dynamic properties of polymers, but due to the limited dynamic properties of a single supramolecular interaction, it is difficult to form synergistic and orthogonal comprehensive properties

preparation example Construction

[0191] In the preparation process of dynamic cross-linked polymers, three methods of mechanical foaming, physical foaming and chemical foaming are mainly used to foam dynamic cross-linked polymers.

[0192] Wherein, the mechanical foaming method is to introduce a large amount of air or other gases into the emulsion, suspension or solution of the polymer to make it into a uniform foam with the help of strong stirring during the preparation of the dynamic crosslinked polymer, and then It becomes a foam material through physical or chemical changes to shape it. In order to shorten the molding cycle, air can be introduced and emulsifiers or surfactants can be added.

[0193] Wherein, the physical foaming method is to utilize physical principles to realize the foaming of the polymer in the preparation process of the dynamic crosslinked polymer, which includes but not limited to the following methods: (1) inert gas foaming method, namely Under pressure, the inert gas is pressed int...

Abstract

A dynamic crosslinked polymer containing a combination supramolecular interaction is disclosed. The polymer contains at least two supramolecular interactions and the degree of crosslinking of at leastone of the supramolecular interactions is above its crosslinked gel point, wherein at least one of the supramolecular interactions is a subject-object interaction, and the dynamic crosslinked polymercan prepare polymer materials with strong reversibility, rich structure and various properties through introduction of the supramolecular interactions with different dynamicity. The difference between different kinds of supramolecular interactions in the dynamic crosslinked polymer makes the polymer exhibit a hierarchical dynamic reversible effect; and the dynamic crosslinked polymer can be usedas a self-repair material, a toughness material, a sealing material, a force transducer material, and the like, thereby being widely applied.

Description

Technical field: [0001] The invention relates to the field of intelligent polymers, in particular to a dynamic cross-linked polymer with combined supramolecular effects. Background technique: [0002] Supramolecular chemistry is the chemistry based on the non-covalent bond interaction between molecules to form molecular aggregates. It mainly studies the molecular aggregates generated by the weak non-covalent bond interactions between molecules and their synergy Assembly, structure and function. Supramolecular polymers are a new field of polymer science research. Based on the weak interaction of supramolecular chemistry and dynamic reversibility, supramolecular polymers are a new class of smart materials. The force of supramolecular interaction is small, the dynamic conditions required by it are relatively mild, and the dynamic performance is good. important role. [0003] At present, the types of supramolecular interactions discovered are becoming more and more abundant, ...
