近来,用纳米材料如有机粘土和碳纳米管来补强聚合物日显重要,关键是基于纳米级层状硅酸盐单片分散性良好时,能有效提高弹性体阻隔和机械性能。但是,如果填料粒子间极性结合很强(尤其是在非极性橡胶中),则纳米粒子在聚合物中的分散就成问题。一个典型例子是,沉淀法白炭黑在高性? Recently, the use of nanomaterials such as organoclays and carbon nanotubes to reinforce polymers is of paramount importance. The key is that based on the good dispersibility of nanoscale layered silicate monoliths, elastomer barrier and mechanical properties can be effectively enhanced. However, if the polarities between filler particles are strongly bound, especially in non-polar rubbers, the dispersion of the nanoparticles in the polymer is problematic. A typical example is precipitation of silica in high?
