Abstract

The invention relates to a new epoxy resin shape memory macromolecule material and a relative preparation method, wherein the material contains liquid crystal epoxy resin monomer and curing agent at stoichiometry, which may further contains curing accelerator of 0-2% consumption of the total accounts of the liquid crystal epoxy monomer and curing agent. Compared with prior shape memory material, the inventive material has the advantages that (1), the thermal responsible temperature can be adjusted by adjusting the side chain and substituted chain of the liquid crystal epoxy monomer or by selecting curing agent, (2), the heat response time is short and the shape recover is rapid, (3), the product can realize saturated shape memory effect, (4) the product has simple preparation and clear structure.

Description

technical field

[0001] The invention belongs to the technical field of shape memory materials, in particular to an epoxy resin type shape memory polymer material and a preparation method thereof. Background technique

[0002] Shape memory refers to the phenomenon that a product with an initial shape can be restored to its original shape after being deformed and fixed by external stimulus means such as heating.

[0003] Since the 1960s, shape memory materials have attracted worldwide attention due to their unique properties, and related research has also developed rapidly. Shape memory materials include shape memory alloys (SMA), shape memory ceramics (SMC) and shape memory polymers (SMP). Compared with SMA, SMP not only has large deformation, easy shaping, and easy adjustment of shape response temperature, but also has the characteristics of heat preservation, good insulation performance, no rust, easy coloring, printable, light weight and low price. But its disadvantages ...
