| Popis: | To improve the compatibility of montmorillonite (MMT) with polymer. A kind of organic intercalation agent was applied in the intercalating organic modification of montmorillonite (OMMT) through ion exchange method, and a kind of silane coupling agent was further used to do the organic treatment. The SEBS/OMMTs composites were also prepared by melt blending. Structure and characterization of the modified MMTs were investigated by Fourier Transform infrared (FT-IR), wide angle X-ray diffraction (WAXRD), and the thermal stability were characterized by Thermogravimetric analysis (TGA). The dispersion status of MMTs were evaluated by scanning electron microscope (SEM) and the composites were tested by universal material testing machine. The FTIR results initial displayed that OMMTs had the absorption peak of organic functional groups. The XRD results showed that compared to Na+-MMT(1.47 nm), the layer spacing of H-OMMT increased to 3.27 nm, the above two results showed the organic modification of MMT had succeed. The results of TGA showed that OMMTs had a weight loss of organics. The SEM demonstrated that H-OMMT had the best dispersion status in SEBS matrix, and Na+-MMT was the worst. |
