Development of Electromagnetic Wave Absorber Pavement Material Basedon Synthetic Resin with Advanced Nanocarbon Materials as Filler

本研究的目的是制备含有碳纳米管的复合材料，并阐明碳纳米管分散的合成树脂复合材料的特性。在本研究中，这种复合材料的制备使用几种类型的沥青乳液作为粘合剂。结果表明，非离子型和阴离子型乳液与所制备的碳纳米管复合后均保持分散状态。但阳离子乳液不能保持分散状态。经过几个额外的系统实验，发现阳离子乳液成功地保留了足够的分散状态，当制备的碳纳米管用酸溶液处理，并随后增量添加的预处理的碳纳米管。当所有碳材料的质量百分比相同时，三种类型的CNT-沥青复合材料在穿透和微波吸收测试中表现出比包括炭黑粉末代替CNT的沥青复合材料更高的性能。

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.
