Abstract
The invention discloses a preparation method of ZnO ink, the ZnO ink, a photoelectric device and a display device. According to the preparation method of the ZnO ink provided by the invention, polar groups in the polar polymer can be coordinated with the surfaces of ZnO particles to coat the surfaces of the ZnO particles, so that irreversible agglomeration of the ZnO particles in a dry state can be effectively prevented; according to the preparation method of the ZnO ink disclosed by the invention, the residual impurities such as the first solvent and the second solvent can be removed through a freeze-drying method in the preparation process of the ZnO ink, and the introduced polar polymer is removed, so that the first solvent in the ZnO stock solution can be effectively removed, new impurities are not introduced, and the prepared ZnO ink has relatively high stability.
