The present disclosure discloses a method of manufacturing silicon dioxide nanoparticles modified by a polymer containing phosphorus and nitrogen, which relates to organic/inorganic hybrid nanoparticles, dispersing SiOin an organic solvent, then adding THPS, stirring, and finally adding p-phenylenediamine, reacting, centrifuging, washing, and drying to obtain silicon dioxide nanoparticles modified by a polymer containing phosphorus and nitrogen. The silicon dioxide nanoparticles modified by the polymer containing phosphorus and nitrogen have effects in flame retardancy, strengthening effect of polymer matrixes, and are expected to be widely used in the halogen-free synergistic flame retardancy of polymer materials.
