| titleOfInvention | High temperature-resistant thermoplastic shape-memory polyimide and preparation method therefor |
| abstract | A high temperature-resistant thermoplastic shape-memory polyimide and a preparation method therefor, related to a polyimide and a preparation method therefor. The present invention aims to solve the problem that an existing shape-memory polymer is inapplicable in a high temperature field due to a low glass transition temperature, T g , and poor thermal properties and thermodynamic properties at high temperatures. The high temperature-resistant thermoplastic shape-memory polyimide is prepared with 4,4'-(hexafluoroisopropylidene)diphthalic anhydride and 4,4'-diaminodiphenylether as reactive monomers and has a structural formula as represented by formula (I). The preparation method: 1. dissolving of 4,4'-diaminodiphenylether monomers; 2. preparation of a sol-gel-like polyamic acid; 3. removal of residual air bubbles; 4. thermal imidization; and, 5. mold releasing. The present invention produces the high temperature-resistant thermoplastic shape-memory polyimide. |
