Abstract

The invention discloses a prepolymer for remodeling bismaleimide resin and its application. The specific preparation is as follows: 2-allylphenyl glycidyl ether and adipic acid are blended in acetonitrile, and an esterification reaction occurs under the condition of a quaternary ammonium salt as a catalyst to obtain a bis(3-( 2‑allylphenoxy)‑2‑hydroxypropyl) adipate; then bis(3‑(2‑allylphenoxy)‑2‑hydroxypropyl) adipate was combined with bis The maleimide is uniformly mixed to obtain a prepolymer for a remodelable bismaleimide resin; the prepolymer is cured to obtain a remodelable shape memory bismaleimide resin. The remodelable shape memory bismaleimide resin prepared by the prepolymer of the remodelable bismaleimide resin of the present invention not only has good shape memory performance, heat resistance and mechanical properties, but also can be used under hot pressing conditions It can be reshaped under the environment, and has broad application prospects in the fields of aerospace, space self-deploying structures, sensors and actuators.

Description

technical field

[0001] The invention relates to a prepolymer for remodeling bismaleimide resin, a preparation method and application thereof, and belongs to the fields of thermosetting shape memory polymers and recyclable polymers. Background technique

[0002] Shape memory polymers (SMPs) are a class of intelligent materials that can deform autonomously by responding to external stimuli (heat, light, electricity, magnetism, solvents), and have the advantages of light weight, high strength, easy processing, diverse response modes, and simple shape control. advantage. Generally speaking, SMPs are divided into two types: thermosetting SMPs and thermoplastic SMPs. Thermosetting SMPs have better mechanical properties, higher thermal transition temperature and better thermal stability than thermoplastic SMPs. Structures, intelligent jet propulsion systems, and high-temperature sensors and actuators have broad application prospects. It is foreseeable that with the development of...
