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.
