碳纳米管(CNT)填充的橡胶复合材料是一类特殊材料,其中由于碳纳米管具有高纵横比,所以预计这种材料会具有极佳的物理性能和导电性能。与之相反,碳纳米管较差的分散性及其与橡胶基质间的弱界面相互作用极大地限制了橡胶复合材料物理性能的提高,而且不能充分利用碳纳米管的超补强能力。干湿混合技术是制备碳纳米管橡胶复合材料的传统技术。大多数情况下不推荐采用干法混合是因为在混合过程中碳纳米管飞扬的粉尘会污染环境,湿法混合需要增加超声波处理步骤使碳纳米管分散在有机溶液中,这可能会导致碳纳米管的破裂。因此非常需要新的技术来制备碳纳米管橡胶复合材料。
Carbon nanotube (CNT) filled rubber composites are a class of specialty materials where the material is expected to have excellent physical and electrical conductivity due to the high aspect ratio of the carbon nanotubes. In contrast, the poor dispersibility of carbon nanotubes and their weak interfacial interaction with the rubber matrix greatly limits the physical properties of the rubber composites and does not make full use of the super-reinforcing ability of carbon nanotubes. Dry-wet hybrid technology is a traditional technique for preparing carbon nanotube rubber composites. In most cases, dry mixing is not recommended because the dust flying from the carbon nanotubes can pollute the environment during the mixing process. Wet mixing requires an additional sonication step to disperse the carbon nanotubes in the organic solution, which can result in carbon nano Tube rupture. Therefore, new technologies are needed to prepare carbon nanotube rubber composites.
