A kind of synthesis method of polyimide containing disulfide bond and OLED display device |
| abstract |
The present disclosure provides a method for synthesizing a disulfide bond-containing polyimide and an OLED display device. The method for synthesizing includes dissolving a mercapto compound with an amino group and a catalyst in a first organic solvent, and slowly dropping them under magnetic stirring. Add an oxidizing agent, and the reaction time is set to purify to obtain a disulfide bond-containing diamine; the disulfide bond-containing diamine, the disulfide bond-free diamine and the tetracarboxylic acid are used in the second organic solvent. A polyamide solution containing disulfide bonds is obtained by polymerization reaction; the polyamide solution containing disulfide bonds is obtained by cyclization reaction to obtain a polyimide containing disulfide bonds. The synthesis method introduces disulfide bonds into polyimide materials through molecular design, and utilizes the dynamic reversible properties of disulfide bonds to endow polyimide with self-healing function. Using disulfide bond-containing polyimide as the functional layer of OLED can repair tiny damages in production and use, and improve production yield and service life. |
