Preparation of Nano-Scale Piece of Sericite by Using Mechanical Exfoliation Method and Ultrasonic Method

Abstract:

The structure of sericite is very stable, so it is hard to peel it directly using traditional methods. In this article, the sericite which was processed through thermal activation, acid treatment, Na-modification and CTAB intercalation was used as raw material to do the exfoliation. The mechanical exfoliation method and ultrasonic method were used respectively to exfoliate the modified sericite. The grain size of final product using mechanical exfoliation method reached 16.6nm and the grain size of final product using ultrasonic method reached 8.1nm. Alongside with the result of TEM images, the ultrasonic method is thought to be better.
