Abstract

The invention discloses a preparation method of a supramolecular polymer film, comprising the following steps: dissolving alkali, lipoic acid and its derivatives in a mixed solution of solvent and water, and dissolving lipoic acid and its derivatives in solvent and water The concentration ratio in the mixed solution ranges from 50g / L to 300g / L, the molar ratio of lipoic acid and its derivatives to alkali is 1:2 to 1:0.5, and the volume ratio of solvent to water is 10:1 to 1:1 , heated to reflux for 1-6 hours, and the filtered powder was dissolved in hot water at 45-90°C. The concentration of the powder dissolved in hot water was 10g / L-2000g / L. It was applied to the substrate and evaporated for 1-6 hours. The film is formed at a temperature of 25-70° C. to obtain the supramolecular polymer film. The raw materials used in the preparation method of the invention are beneficial to the human body, biocompatible, widely sourced, cheap and easy to obtain, and have industrial feasibility.

Description

technical field

[0001] The invention relates to the field of chemical technology, in particular to a method for preparing a supramolecular polymer film with humidity response and recyclability. Background technique

[0002] Obtaining supramolecular polymers with ideal structures and functions by controlling the dynamic self-assembly process of small molecules has become a current scientific research hotspot, especially from the perspective of structural engineering to design molecular structures to obtain controllable self-assembly of functional materials. Previous research work often included complicated organic synthesis preparation processes, which made it difficult to carry out the research work smoothly. In recent research work, it was found that the synergistic effect of amorphous polymer chains and ordered crystalline phase packing can promote supramolecular polymers based on lipoic acid and its derivatives to form rubber materials with excellent self-healing propert...
