| titleOfInvention | Dianhydride monomer containing 2, 5-furandimethanol residue and preparation method thereof, polyimide film and preparation method thereof |
| abstract | The invention relates to the technical field of polyimide films, in particular to a dianhydride monomer containing 2, 5-furandimethanol residues and a preparation method thereof, and a polyimide film and a preparation method thereof. The dianhydride monomer containing the 2, 5-furan dimethanol residue provided by the invention contains a furan ring structure with certain rigidity, so that the dianhydride monomer has certain mechanical strength and thermal property. The 2, 5-furandimethanol is mainly derived from cellulose and hemicellulose, is a biological base material with excellent performance, can be biodegraded, is green and environment-friendly, and can be applied to the field of degradable engineering plastics; meanwhile, the polyimide has good solubility, so that the processing condition and the recycling rate of the polyimide can be improved. The invention also provides a polyimide film. The polyimide in the polyimide film contains 2, 5-furandimethanol residues, has excellent optical performance, and can be applied to the photoelectric field. |
