A self-healing light-controlled plastic polyurethane elastomer material, its preparation and application

Abstract

The invention discloses a polyurethane elastomer material and a preparation method thereof. By taking hexaarylbiimidazole (HABI) photochromic molecules and polyhydric alcohol as cross-linking agents of an elastomer material, the polyurethane elastomer material with a double-cross-linking network structure is constructed, and an intelligent deformation polyurethane material having rapid response toultraviolet light is correspondingly obtained and has a self-healing function. A polyurethane elastomer has good mechanical and physical properties of tenacity, ductility, fatigue resistance and thelike, is taken as an intelligent material and has potential application markets in drivers, software robots, artificial biological organs, sensors, manufacturing industry, medical treatment, wearableequipment, medical treatment instructions and the like.

Description

technical field

[0001] The invention belongs to the technical field of flexible intelligent driving materials, and in particular relates to a self-healing light-controlled plastic polyurethane elastomer material, its preparation method and application. Background technique

[0002] Self-healing photoplastic polyurethane elastomers belong to the category of polymer smart actuation materials, also known as actuators or artificial muscles, which respond to external stimuli and can change their shape and size. In recent years, with the deepening of research and the increasing demand for production and living, the research on flexible actuators and stimulus-responsive materials is booming. Among them, polymer materials are widely used in the field of intelligent material research and development due to their advantages of low manufacturing cost and easy processing. play a leading role in. These materials have the potential to revolutionize healthcare, wearable devices, artificia...
