摘　　要：近年来,磁性流体材料因其可以在外界磁场附加下变换出不同形状的特性而被广泛应用于科技馆展示、生物医药、传感器、吸波材料、动密封等领域中,已成为多个领域应用的热点材料。但目前展示用的磁性流体大多以黑色磁性流体为主,无法呈现彩色图案,达不到最佳的展示效果,如果制备出颜色可控的磁性流体可以极大的丰富展示效果。本文采用金属乙酸盐为原料,水热沉淀法合成了Fe_(3)O_(4)纳米颗粒,并在其表面包覆了易于染色的SiO_(2),通过对Fe_(3)O_(4)@SiO_(2)染色,制备了多种颜色的油基磁性流体;使用XRD,FT-IR,TEM,VSM等表征手段进行了详细分析,制备的颜色可控的纳米磁性流体有望在科技馆展示装置中普及使用。In recent years,magnetic fluid materials have been widely used in science and technology museum exhibition,biomedicine,sensor,absorbing materials,dynamic sealing and other fields because they can transform different shapes under external magnetic field addition,and have become hot materials in many fields.However,most of the magnetic fluids used in the display are mainly black magnetic fluids,which cannot present the color pattern,and cannot achieve the best display effect.If the magnetic fluid with controllable color is prepared,it can greatly enrich the display effect.In this paper,Fe_(3)O_(4)nanoparticles were synthesized by metal acetate and hydrothermal precipitation,covering the surface with SiO_(2).Oil-based magnetic fluids in multiple colors were prepared by staining for Fe_(3)O_(4)@SiO_(2).Detail analyse by XRD,FT-IR,TEM,VSM,etc,according to the research,color-controlled nanomagnetic fluids are expected to be used in exhibition equipment.
