ABSTRACT
Random carbon nanotube (CNT) networks have raised a continuously increasing interest among a broad and multidisciplinary community of researchers. This chapter demonstrates a reliable and reproducible spray deposition process for the fabrication of CNT films exhibiting state-of-the-art performance. Spray technology is used in a wide variety of applications such as surface coating, humidification, combustion, and others. For the fabrication of highly uniform and smooth CNT films, the final CNT solution is spray deposited onto plain glass substrates. The surface characterization and thickness measurements of fabricated CNT films were performed with an atomic force microscope operated in a tapping mode. Prior to the adoption of CNT films in any specific application, it is necessary to optimize and evaluate the elementary film performance on the basis of some primary figures of merit and their dependence on different process parameters. An accurate examination of the surface characteristics at the nano-scale is required for a detailed evaluation of the pristine CNT film quality.
