Abstract:
Filled clusters of cobalt-phthalocyanine/Iron nanoparticles have been obtained using method of organic-inorganic composite in situ with cobalt-phthalocyanine(CoPc) and carbonyl iron.The filled clusters consist of α-Fe nanoparticles in the inner of the nanocomposite particle and interface of CoPc layers.And interface of theα-Fe nanoparticles and surface of the clusters are completely covered by CoPc layers.Diameters of the-α Fe nanoparticles are ranged from 10nm to 15nm.And average diameter of the clusters was 1.4μm including thickness of CoPc layers from 50 to 150nm.For the filled clusters,the density is 3.664g/cm3,the saturatation intensity of magnetization is 76.3Am2/kg,and the coercive force is 4.15kA/m.Thermal stability of the filled clusters is excess of 150℃。There is a long-term stability of anti-sedimentation for the magnetorheological suspension consisting of the filled clusters and methylic silicone oil.

摘要:
采用有机/无机原位复合技术,将酞菁钴(CoPc)的DMF溶液与Fe(CO)5混合、加热回流制备出稳定的、规则球形的、平均粒径为1.4μm的酞菁钴/铁纳米填充母粒。其内部为10~15nm的μ-Fe填充,外部为厚50~150nm的酞菁钴层包覆。纳米填充母粒的填实密度为3.664g/cm3,比饱和磁化强度为76.3Am2/kg,矫顽力为4.15kA/m。纳米填充母粒的热稳定性高于150℃,与甲基硅油组成的磁流变液有良好的抗沉降性。
