摘要
本论文采用氧化沉淀法制备纳米Fe_(3)O_(4)粒子,将正硅酸乙酯处理磁粒子,获得Fe_(3)O_(4)@SiO_(2)纳米粒子,然后用3-氨丙基三乙氧基硅烷(APTES)对纳米复合粒子进行改性,获得表面带有-NH2的磁性纳米粒子,然后将氧化石墨烯(GO)涂覆在经过改性的纳米复合磁粒子上,获得修饰有不同有机分子的复合纳米磁粒子。最后运用了傅立叶红外、XRD、元素分析表征对其进行分析。结果表明,成功获得修饰有不同有机分子的Fe_(3)O_(4)@SiO_(2)@GO复合纳米磁粒子。
In this thesis,nano-Fe_(3)O_(4) particles were prepared by oxidation precipitation method.The magnetic particles were treated with ethyl orthosilicate to obtain Fe_(3)O_(4)@SiO_(2) nanoparticles,and then the nano-composite particles were modified with 3-aminopropyltriethoxysilane(APTES).Magnetic nanoparticles with-NH_(2) on the surface were obtained,and then graphene oxide(GO)was coated on the modified nano-composite magnetic particles,composite nano magnetic particles modified with different organic molecules were prepared.At last,Fourier infrared,XRD and Elemental analysis were used to analyze it.The results show that Fe_(3)O_(4)@SiO_(2)@GO omposite modified with different organic molecules are successfully obtained.
