OMMT/IIR纳米复合材料结构与性能的研究

采用熔体插层法制备有机蒙脱土（OMMT）/IIR纳米复合材料。试验结果表明，OMMT/IIR纳米复合材料是插层型纳米复合材料；与无机粘土/IIR微米复合材料及IIR相比，OMMT/IIR纳米复合材料具有良好的物理性能，且其物理性能均随OMMT用量的增大而明显提高；与IIR相比，OMMT/IIR纳米复合材料具有优异的气密性。;The organomontmorillonite(OMMT)/IIR nanocomposites were prepared by melt intercalation and their properties were investigated.The results showed that the molecular chains of IIR were intercalated into the nano-OMMT layers in the composites；compared with the pure IIR vulcanizate or inorganic clay/IIR microcomposite，the prepared OMMT/IIR nanocomposites possessed better physical properties，which improved with the increase of OMMT content；and compared with the pure IIR vulcanizate，the prepared OMMT/IIR nanocomposites had more excellent air-tightness
