一种制备磁性Co纳米颗粒的新方法

A New Method for Preparing Magnetic Cobalt Nanoparticles

采用创新的、特殊的实验方法,实现在液相化学反应中精确控制磁性纳米颗粒的生长过程:将物理与化学方法相结合,在传统的液相化学反应的基础上引入物理作用,达到对磁性纳米颗粒生长大小的控制。对其形状和大小进行了透射电镜分析,确认Co纳米粒子为球形,平均粒径为14nm。并对其磁特性进行了初步测试分析。

A new and special experimental method is applied to the preparation of magnetic nanoparticles. We use both physical and chemical means to find a way to control the size of nanoparticles. The morphology of the nanoparticles is sudied by TEM photographs and we find the shape of Co nanoparticles is spherical. The average particle size is around 14 nm. The magnetic properties of the nanoparticles are measured by AGM.
