碳纳米管海绵的压缩性能:实验和建模
首发时间:2011-09-26
摘要:碳纳米管海绵体是由相互交错的碳纳米管组成的三维结构,在复合材料以及环境保护方面具有潜在应用。具有厘米量级尺寸的碳纳米管海绵体已经通过化学气相沉积(CVD)方法成功制备并且研究了碳纳米管海绵体的机械压缩性能。为了深入了解碳纳米管海绵体的微观结构以及其中的碳纳米管的连接情况,提出了一个简单的理论模型来了解碳纳米管的排列以及相互连接情况。可以应用此模型很好地解释以及预测碳纳米管海绵体的机械性能。

Compressive mechanical properties of carbon nanotube sponges: Experiments and modeling
Abstract:Carbon nanotube (CNT) sponges are three-dimensional frameworks of interconnected CNTs with great potentials in composite and environmental applications. CNT sponges with lateral sizes of centimetres have been prepared through chemical vapour deposition (CVD), and their compressive mechanical properties are studied. To gain deep insight on the microstructure and how CNTs are connected within the sponges, we propose a simple theoretical model to understand the arrangement as well as the interconnection of CNTs.
Keywords: carbon nanotube sponges compressive modeling
