| titleOfInvention | A kind of preparation method of organic flexible screen substrate material |
| abstract | The invention relates to the technical field of OLED, and discloses a preparation method of an organic flexible screen substrate material, comprising the following steps: drying the shells of swimming crabs to a constant weight, boiling them in a NaOH solution and filtering; transferring the filter residues into a nitric acid solution Soak, filter after soaking; clean the filter residue to neutrality, then transfer to diethylenetriaminepentaacetic acid aqueous solution, add N,N-dimethylformamide and hydrogen peroxide in turn, adjust the pH of the solution to alkaline, and stir the reaction Filtration; the filter residue is washed to neutrality and then transferred to acetic acid solution, ultrasonically extracted and centrifuged, and the water in the supernatant is evaporated to dryness to obtain DPTA-modified chitin nanofibers, that is, the organic flexible screen substrate material. The organic flexible screen substrate material obtained by modifying chitin nanofibers with DPTA in the present invention has good optical and mechanical properties, and has strong adsorption properties for lanthanide elements. |
