摘　　要：采用溶液插层法制备了丁基橡胶/有机黏土纳米复合材料,并用透射电子显微镜和X射线衍射仪研究了该纳米复合材料的形态结构。结果表明,丁基橡胶/有机黏土纳米复合材料是插层型的纳米复合材料。与丁基橡胶相比,该纳米复合材料具有优异的力学性能和气体阻隔性能,并且这2种性能均随有机黏土用量的增加而增强。填料的形状会对该纳米复合材料的气体阻隔性能产生影响。Isobutylene-isoprene rubber (IIR)/organic clay nanocomposites was prepared by solution intercalation, and its morphological structure was investigated by transmission electron microscopy(TEM) and X-ray diffraction (XRD).The results showed that intercalated clay layers existed in these nanocomposites. Compared with corresponding IIR, the IIR/ organic clay nanocomposites exhibited outstanding mechanical performances and improved gas barrier properties, which were likely attributed to the nanometer scale dispersion and high aspect ratio of clay layers. The mechanical properties of IIR/ organic clay nanocomposites improved with the increase of amount of clay. The shape of fillers was the mainly factor influencing the gas barrier property.
