In order to prepare inorganic functional nanoparticle structure formation in block co-polymer, the effect of surface modification on the packing structure of nanoparticles in polymer was investigated. Block co-polymer, PEO-b-PS were used for matrix and 3 kinds of silica nanoparticles with different surface modification were mixed into PEO-b-PS. After the observation micro phase segregation of prepared block co-polymer by using nuclear magnetic resonance, NMR and other methods, surface modified silica nanoparticles were mixed into polymer and prepared polymer composite. The dispersion and array of nanoparticles in polymer composite depended on the modified silica surface molecular structure.
