摘要

磁性微球是一种具有磁响应性

表面富含官能团的复合性功能材料。用生物酶解法

将玉米淀粉水解为多孔淀粉

再将Fe3O4磁流体通过多次振荡、离心

填充到多孔淀粉的毛细孔径内

制备出粒径分布在10~15 μm 范围内的磁性多孔淀粉微球。通过扫描电镜(SEM)观察和傅里叶红外光谱仪测定发现

该微球呈椭圆形或球形

表面富含羟基和羧基等官能团

并可在水溶液中稳定均匀地分布。在外部磁场的作用下

具有较强的磁响应性。

Abstract

Magnetic microsphere is a composite magnetic material with rich surface functional group. Porous starch was prepared by corn starch hydrolysis using biological enzymatic method

then 10—15 μm magnetic porous starch microspheres can be obtained by mixing Fe3O4 magnetic fluid and porous starch by multiple shake and centrifugation. Oval or spherical magnetic microspheres with rich hydroxyl and carboxyl functional groups can be observed by SEM and FTIR. The obtained magnetic microspheres can be uniformly distributed in aqueous solution and have strong magnetic response in an external magnetic field.
