| Abstract: | The dispersibility of vermiculite is the key factor that affects the application of vermiculite. In this paper,the milled natural vermiculite was pillared by organic quaternary ammonium salts. Then the pillared vermiculite was ground and homogenized under the existence of dispersive agent to form a stable vermiculite hydrosol system. Small angle X-ray diffraction (SA-XRD),fourier transform infrared spectroscopy (FTTR),and thermogravimetric analyses (TGA) were used to characterize the structure and thermal property of the vermiculite. The results indicate that the exfoliated vermiculite is successfully obtained. The analyses of laser particle size analyzer,transmission electron microscpe (CTEM),and Tyndan phenomenon analyzer demonstrate that the vermiculite hydrosol prepared is a stable hydrosol system. |
