preparation example Construction

[0206] In the preparation process of dynamic polymer, three methods of mechanical foaming method, physical foaming method and chemical foaming method are mainly used to foam dynamic polymer.

[0207] Among them, the mechanical foaming method is to introduce a large amount of air or other gases into the emulsion, suspension or solution of the polymer with the help of strong stirring during the preparation of the dynamic polymer to make it a uniform foam, and then through physical Or chemical changes make it shape and become a foam material. In order to shorten the molding cycle, air can be introduced and emulsifiers or surfactants can be added.

[0208] Wherein, the physical foaming method is to use physical principles to realize the foaming of the polymer during the preparation of the dynamic polymer, which includes but not limited to the following methods: (1) inert gas foaming method, that is, after adding Press the inert gas into the molten polymer or pasty material under ...

Abstract

A dynamic polymer containing a combination supramolecular interaction is disclosed. The polymer contains at least two supramolecular interactions, wherein at least one of the supramolecular interactions is an ion-dipole interaction, and the dynamic polymer can 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 polymer makes the polymer exhibit a hierarchical dynamic reversible effect; andthe dynamic polymer can be used as 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 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, and there are...
