Abstract
Disclosed in the present invention are a chiral azobenzene polymer crosslinked thin film and preparation method therefor and application thereof. The present invention relates to a novel super-molecular chiral construction and chiral immobilization method based on an achiral side chain type azobenzene polymer thin film. According to the present invention, limonene steam is utilized to perform chiral induction on a polymer thin film at a high temperature, and then formaldehyde steam is utilized to perform acetal reaction with hydroxyl in an acidic environment to achieve crosslinking; and then differences in the stability of the super-molecular chirality of the polymer thin film before and after crosslinking is studied under the conditions of light, heat and good solvent dissolution, and the self-repairing properties of microcosmic helical chirality is researched. The crosslinked thin film prepared by the present invention has good chiral properties, and excellent solvent resistance, heat resistance, and self-repairing properties.
