A kind of method that filler is added into polymer material of target system of the invention, nanoparticle to be added in the polymer material that can not or be difficult directly to add nanoparticle by means of group in a composition, the polymer material is thermoplastic material, silica dioxide granule of the composition by plasticizer and average particle size less than or equal to 150 nm forms, the surface-modified processing of silica dioxide granule, so as to compatible with plasticizer, the content of the silica dioxide granule is 10 wt% to 80 wt%, the content of the plasticizer is 90 wt% to 20 wt%, the silica dioxide granule colloidal dispersion is in the composition.Nanoparticle can be mixed into any polymer material by simple mode by the present invention. |
