Abstract
A composite material, a preparation method thereof and a photoelectric device are disclosed, and related to a field of display technologies. The composite material includes an inorganic particle and a perfluorosulfonamide, wherein the inorganic particle is connected to the perfluorosulfonamide by a chemical bond, and a chemical formula of the perfluorosulfonamide is R—SO2—NH2. Perfluorosulfonamide in the composite material could reduce the surface defects of the inorganic particle, inhibit the growth and agglomeration of the inorganic particle, and thus improve the storage time of the inorganic particle.
