摘　　要：运用自制的两种新型小分子液晶插层剂对蒙脱土进行有机化修饰,并用IR,XRD,TG及TEM等对有机蒙脱土结构和性能进行了表征与分析。结果表明:有机蒙脱土的层间距由1.00 nm分别增大到2.50 nm和2.88 nm,且能分散均匀,排列疏松,耐热性能也有了显著提高。Two new liquid crystals intercalation reagent were used to modify the natural montmorillonite in order to get mesomorphic phase. Their structures and properties were characterized by IR, XRD, TG and TEM. The results showed that the spacing of layers of organophilic montmorillonite were increased from 1.00 nm to 2.50 nm and 2.88 nm, respectively. Besides, their homogeneous dispersion and thermal stability properties were significantly increased.
