采用喷墨打印技术制备了单壁碳纳米管薄膜。原子力显微镜（AFM）已被用来研究这些层的形态。喷墨打印薄膜由小的、随机取向的纳米管岛组成，其形貌取决于衬底表面的性质。在室温下测量了薄膜的平面内电特性。电流对电压数据表现出非线性行为，这可以拟合到普尔-弗伦克尔电导率的理论模型。还报告了使用薄层检测酒精蒸气的初步测量结果。(C) 2008 Elsevier Ltd版权所有。
Thin films containing single-wall carbon nanotubes (SWCNTs) have been prepared using the inkjet printing (IJP) technique. Atomic force microscopy (AFM) has been used to investigate the morphology of these layers. The inkjet printed films consisted of small, randomly-oriented islands of nanotubes, the topography of which was dependent on the nature of the substrate surface. The in-plane electrical characteristics of the films were measured at room temperature. The current versus voltage data exhibited non-linear behaviour, which could be fitted to the theoretical model for Poole-Frenkel conductivity. Preliminary measurements are also reported on the use of the thin layers to detect alcohol vapour. (C) 2008 Elsevier Ltd. All rights reserved.
