Summary: | The invention provides a quantum dot polymer compound and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing oil-soluble quantum dots, a polymer material, a mercaptan alkene polymer and an auxiliary agent at a processing temperature, and cooling the mixture to room temperature to form the quantum dot polymer compound. According to the preparation method, with a high polymer material as an environment, different ligand materials and quantum dot materials are added and different ligand exchanges are carried out on the surfaces of the quantum dots, and finally, the high-stability quantum dot high polymer composite material is obtained; because the surface mercaptan alkene polymer is well adsorbed on the surfaces of the quantum dots, and meanwhile, molecular chain segments among the ligands are relatively long, so that the quantum dots are mutually wound to further form a barrier, the ligand is more effectively prevented from falling off, and the quantum dot mater |
