polymer复合材料的AC电导率:一种用于鉴定粗多壁碳纳米管样品的有效验证工具
AC conductivity of polymer composites: an efficient confirmatory tool for qualifying crude multi-walled carbon nanotube-samples
摘要:
目前的通信强调,交流电导率测量的多壁碳纳米管(MWNTs)-聚合物复合材料是一个非常有前途的表征工具,用于鉴定任何原油MWNT-sample电弧合成。它将石墨结构与MWNT的石墨结构区分开,并反映了样品中存在的近一维结构和无序的相对量。这一新的协议将有助于发展更直接和定量的标准,通过不同的技术合成的MWNTs的资格,并肯定会添加到概念理解在可视化的确切作用,不同的控制参数影响MWNTs的生长。
英文摘要:
The present communication highlights that ac conductivity measurement of the multi-walled carbon nanotubes (MWNTs)-polymer composites is a very promising characterizing tool for qualifying any crude MWNT-sample synthesized by electric arc. It distinguishes graphite structures from that of the MWNTs and reflects the relative amount of nearly one-dimensional structures and disorders present within the samples. This new protocol would help in evolving more direct and quantitative criteria for qualification of MWNTs synthesized through diverse techniques and will definitely add up to the conceptual understanding in visualizing the exact roles of different controlling parameters affecting the growth of MWNTs.
