The purpose of this study is to prepare composite materials containing CNTs and to elucidate the characteristic properties of CNTs-dispersed synthetic resin composites. In the present study, such composites were prepared using several types of asphalt emulsions as a binder. As a result, both nonionic and anionic emulsions kept dispersed state, when combined with as-prepared CNTs. However, cationic emulsions failed to keep dispersed state. After several additional systematic experiments, it was found that cationic emulsion successfully retained an adequate dispersion state, when as-prepared CNTs were treated with acid solution and the following incremental addition of the pretreated CNTs. The three types of CNTs-asphalt composites demonstrated higher performances in both penetration and microwave-absorption tests than asphalt composites including carbon black powder instead of CNTs, when the mass percentage of all carbon materials was the same.

本研究的目的是制备含碳纳米管的复合材料，并阐明碳纳米管分散合成树脂复合材料的特性。在本研究中，采用几种类型的沥青乳液作为粘结剂制备了这种复合材料。因此，当与制备好的CNTs结合时，非离子和阴离子乳剂均保持分散状态。然而，阳离子乳剂未能保持分散状态。经过几次系统的实验，我们发现，将制备好的CNTs用酸溶液处理，然后再添加预处理后的CNTs，阳离子乳液成功地保持了足够的分散状态。在所有碳材料的质量百分比相同的情况下，三种碳纳米管-沥青复合材料在渗透和微波吸收测试中的性能都高于含炭黑粉而不含碳纳米管的沥青复合材料。
