A kind of gallic acid bio-based polyimide and its preparation and application |
| abstract |
The invention discloses a gallic acid bio-based polyimide and its preparation and application. The chemical structural formula of the gallic acid bio-based polyimide is shown in formula (I). The main chain of the polyimide prepared by the invention contains nitrogen and sulfur heteroatoms, has large modification space and strong processability; and its thermal stability and mechanical strength are close to those of the existing bio-based polyimide. The transmittance of imide film to 450nm visible light can reach 92%, which is far better than traditional polyimide, and can be used in flexible display devices, industrial insulation and environmental protection packaging, separation film devices, etc. |
