摘要 描述了一种基于液相沉积法制备纳微核壳粒子的新方法,即以聚(苯乙烯-丙烯酸)乳胶粒子为模板,利用静电相互作用和液相沉积的方法,将氢氧化铁包覆在模板粒子表面,形成聚(苯乙烯-丙烯酸)/铁的氧化物核壳纳米复合粒子。通过TEM和SEM观察,Fe2O3晶粒在模板粒子表面生长并呈草莓状,壳层厚度均匀。该特殊结构有利于通过煅烧除核的方法获得硬质空心磁球。 A novel and simple liquid deposited process used to produce composite particles is demonstrated. The poly(styrene-acrylic acid) colloid spheres were used as the templates coated by ferric compound. SEM,TEM images show that Fe2O3 crystal coats on the poly(styrene-acrylic acid) colloid particle and forms a strawberry like shape, which is propitious to fabricate hollow particles by calcination.
