天然水镁石纳米纤维的分散

Dispersion of Natural Brucite Nano-fibers

以OT做分散剂,通过搅拌分散、球磨、超声波分散等方法分散制备出天然水镁石纳米纤维。并采用扫描电镜(SEM)、透射电镜(TEM)对制备出的纳米纤维进行了表征。结果表明,制备出的水镁石纳米纤维单根直径在30nm左右,非单根形式存在的水镁石纤维堆积体的直径约50-150nm。天然水镁石矿物纤维经本文的分散方法处理,可获得具有实用价值的纳米材料。

The natural brucite nano-fibers were obtained by mechanical stirring, ball milling and ultrasonic methods with OT as dispersant. The prepared nano-fibers were characterized by using SEM and TEM. The images of SEM and TEM indicated that the diameter of the single fiber is around 30nm and the diameter of the non-single fiber is from 50nm to 150nm. Compared with the methods for synthesizing nano-fibers ,the method used for prepare natural nanofibers mentioned in this article has priority in yield and cost.
