OMMT/NBR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）/NBR纳米复合材料，并对其微观结构及性能进行研究。结果表明，采用熔体法制备的OMMT/NBR复合材料，NBR大分子链插入OMMT片层中，OMMT在NBR基体中呈纳米级分散；与未加OMMT的NBR硫化胶相比，OMMT/NBR纳米复合材料的物理性能明显改善，相同剪切变形下的OMMT/NBR纳米复合材料的储能剪切模量较大；随着OMMT用量的增大，OMMT/NBR纳米复合材料的物理性能提高。;The modified organic montmorillonite (OMMT)/NBR nano-composites were prepared by melt intercalation and the microstructure and properties of nano-composites were investigated.The results showed that the molecular chain of NBR was intercalated into the OMMT layers in the OMMT/NBR nano-composites prepared by melt intercalation，and OMMT was dispersed in NBR matrix on nano-scale；the physical properties of OMMT/NBR nano-composites improved significantly and the storage modulus was higher under the same shearing deformation when compared to those of NBR vulcanizate without OMMT；and the physical properties of OMMT/NBR composites improved as the addition level of OMMT increased
