Preparation and Characterization of Sepiolite Nanofibers by Microwave Chemical Methods

Abstract:

The sepiolite samples were defibered by using microwave chemical technique, and then different sepiolite samples were obtained with different treatment process. The effect of reaction time on the defibering for sepiolite fiber bundles was studied systematically. Through characterization by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscope (FTIR), it was found that the defibered sepiolite samples had an average diameter of about 100 nm and length greater than 20μm. The defibering effect of sepiolite samples as prepared reached optimum at the reaction time of 13 min, and the structural stability of sepiolite was kept after defibering treatment.
