| titleOfInvention | A kind of polyimide/reduced graphene oxide composite material and its preparation method and application |
| abstract | The invention belongs to the technical field of shape memory materials, and in particular relates to a polyimide/reduced graphene oxide composite material and its preparation method and application. The present invention provides a polyimide/reduced graphene oxide composite material, comprising cross-linked polyimide and reduced graphene oxide dispersed in cross-linked polyimide; the polyimide has the formula Structure shown in I. In the present invention, the reduced graphene oxide is used as a photothermal filler, which can quickly absorb light energy after being irradiated by near-infrared light, and release heat to convert light energy into heat energy. The released heat energy will make the polyimide matrix realize the shape memory effect, achieve the effect of light-driven deformation, and realize the remote control to activate the shape memory effect. Wherein, R has the structure shown in formula Ⅰ-1: However, n is an integer of 9-11. |
