| 英文摘要 | Palygorskite was dispersed by various organic solvents and water, and the effects of solvent types on its microstructure, dispersion degree, and colloidal properties were investigated by infrared spectroscopy (IR), x-ray diffraction (XRD), and nitrogen adsorption-desorption isotherm (BET), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and rheological analyses. It was found that dimethyl sulfoxide and dimethyl formamide molecules may attach onto the surface of palygorskite and cause a complete disappearance of micropores. Solvent parameters govern the dispersion degree of palygorskite, and dimethyl sulfoxide and dimethyl formamide are good solvents to disperse palygorskite aggregates in contrast to ethanol and isopropanol. Colloidal stability and rheological tests suggested dimethyl sulfoxide-dispersed palygorskite can form more stable suspension with higher shear stress and modulus, but isopropanol-dispersed palygorskite may rapidly subside in suspension and show poor colloidal properties. |
