摘要: 利用Stober方法制备不同粒径分布的单分散二氧化硅（nSiO₂），用氨基改性剂对其进行表面改性，将改性前后的nSiO₂粒子分散于聚乙二醇（PEG）中制备PEG/nSiO₂复合体系，并用透射电子显微镜（TEM）、综合热重分析仪（TG）对nSiO₂粒子的形貌及热性能、PEG/nSiO₂复合体系的流变性能进行表征.结果表明：所制备的nSiO₂粒子的粒径为50~300 nm范围，粒子分布均一，通过控制反应物的配比有效控制其粒径；N-氨乙基-γ-氨丙基三甲氧基硅烷“铆接”在nSiO₂粒子表面，氨基改性成功；所制备的PEG/nSiO₂复合体系的流变性能和nSiO₂粒子的粒径和含量相关联，总体规律是黏度随频率增大.粒径对剪切增稠体系影响很大，最佳粒径在120 nm附近.

Abstract: With the use of silica monodisperse Stober with different particle size distribution was prepared, and then with an amino modifier on silica (nSiO₂) surface modification was prepared, and finally nSiO₂ particles before and after modification were dispersed in polyethylene glycol (PEG) and prepared in the PEG/nSiO₂ composite system, and on the morphology and thermal properties nSiO₂ prepared particles were characterized by Huck rheometer and rheological properties of polyethylene glycol/nSiO₂ composites were investigated with a transmission electron microscope (TEM), integrated thermal gravimetric analysis (TG). The results showed that:particle diameter nSiO₂ prepared in the range of 50~300 nm, a uniform particle distribution, by controlling the ratio of reactants to the particle diameter was effectively controlled; N-aminoethyl-γ-aminopropyl trimethoxy Silane was "riveted" in the nSiO₂ particle surface; The rheological properties of the prepared PEG/nSiO₂ composite system was related to the particle size and the content of nSiO₂ particles,the general rule was that the viscosity increases with the increase of frequency.The particle size effect on shear thickening system was large and the best partide diameter was in the 120 nm particle size nearby.
