| 摘 要： | 将碳纳米管(CNTs)及其它配合剂制成悬浮液,与丁苯胶乳共混,然后利用喷雾干燥法制备CNTs/粉末丁苯橡胶复合材料,检测其热学性能,并进行相应的理论分析。结果表明,随着CNTs加入量的增加,橡胶复合材料的热分解温度逐渐增加,CNTs/橡胶复合材料的热导率逐渐提高,当CNTs体积百分比含量约为22%,即CNTs加入量为60 phr时,与纯胶样品相比,复合材料的热导率提高近1倍。理论分析表明,由于CNTs自身的弯曲和缠绕以及混酸氧化对CNTs自身导热性能的破坏,复合材料热导率的实测值与理论计算值存在一定差距。

| Abstract: | Carbon nanotubes(CNTs)/styrene-butadiene rubber(SBR) composites were prepared by spray drying method with the suspension of acid-treated CNTs and vulcanizing reagents in SBR latex.Thermal properties of the composites were tested and corresponding theoretical analysis were discussed.Experimental results show that the introduction of CNTs into SBR matrix is benificial to improve thermal stabilities of the composites and thermal decomposition temperatures and thermal conductivities of the composites are gradua... |
