Abstract

We report a simple method for the preparation of magnetically-functionalized lens-like and donut-shaped polymeric microparticles, based on spreading a magnetite-doped paraffin-polymer solution at the air/water interface in the presence of an external magnetic field. We examine the parameters that affect the particle morphology and interfacial aggregation behaviour.

摘要

我们报道了一种制备磁性功能化的透镜状和甜甜圈状聚合物微粒的简单方法，该方法基于在外部磁场存在的情况下，将掺杂磁铁矿的石蜡-聚合物溶液铺展在空气/水界面上。我们研究了影响颗粒形态和界面聚集行为的参数。
