摘　　要：利用三甲基氯硅烷修饰的核壳结构Fe_3O_4@TiO_2复合纳米颗粒来稳定Pickering乳液,并对乳液的磁响应性和光响应性进行了评价,结果表明:Fe_3O_4@TiO_2复合纳米颗粒稳定的Pickering乳液具有良好的磁响应性和光响应特性。Fe3O4@TiO2 core-shell structured composite nanoparticles were successfully modified by trimethylchlorosilane to stabilize pickering emulsions.Analyzing the magnetic-field-responsive properties and the UV-light-responsive properties,it was confirmed that pickering emulsions stabilized by Fe3O4@TiO2 core-shell composite nanoparticles not only owned good magnetic response,but also had the ability of light response.The novel pickering emulsions stabilize by nanoparticles would provide unique opportunities for the application of intelligent emulsions.
