Abstract
Provided is a composite material and a preparation method thereof, and a preparation method of a light-emitting device. The composite material includes a nanoparticle, a temperature-responsive polymer, and a solvent, the temperature-responsive polymer has a first gelation critical temperature, and when the temperature is lower than the first gelation critical temperature, the temperature-responsive polymer and the solvent are cross-linked to form a network structure, so that the movement and mutual aggregation of the nanoparticle is avoided, thereby improving the dispersity of the nanoparticles in the composite material.
