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.

为了在嵌段共聚物中制备无机功能纳米粒子结构，研究了表面改性对纳米粒子在聚合物中堆积结构的影响。以嵌段共聚物PEO-b-PS为基体，将3种不同表面改性的SiO2纳米粒子混合到PEO-b-PS中。采用核磁共振、核磁共振等方法对制备的嵌段共聚物进行微观相分离观察后，将表面改性的二氧化硅纳米粒子混入聚合物中，制备了聚合物复合材料。纳米粒子在聚合物复合材料中的分散和排列取决于改性后的二氧化硅表面分子结构。
