利用美国海军研究实验室开发的基质辅助脉冲激光蒸发（MAPLE）工艺，成功制备了碳纳米管和碳纳米管复合薄膜。该过程包括将薄膜材料溶解或悬浮在挥发性溶剂中，将混合物冷冻以形成固体目标，并使用低通量脉冲激光将目标蒸发以沉积在真空系统中。蒸发溶剂的集体作用使聚合物/纳米管复合材料脱离目标物。然后将挥发性溶剂抽走，使薄膜材料留在基材上。通过这种技术，单壁纳米管（SWN）已经从靶转移到衬底上。SWN在沉积过程中没有明显的损伤。以SWN与聚合物结合为目标材料，制备了SWN/聚苯乙烯和SWN/聚乙二醇复合薄膜。这些薄膜可以使用相同的靶材和沉积条件沉积在各种衬底上，例如Si、玻璃、塑料和金属。SEM显微图显示，SWN均匀分布在薄膜中。使用简单的接触掩模，可以生产直径为20um的SWN复合薄膜。
Using the Matrix-Assisted Pulsed Laser Evaporation (MAPLE) process developed at the Naval Research Laboratory, carbon nanotubes and carbon nanotube composite thin films have been successfully fabricated. This process involves dissolving or suspending the film material in a volatile solvent, freezing the mixture to create a solid target, and using a low fluence pulsed laser to evaporate the target for deposition inside a vacuum system. The collective action of the evaporating solvent desorbs the polymer/nanotube composite from the target. The volatile solvent is then pumped away leaving the film material on the substrate. By using this technique singlewall- nanotubes (SWN) have been transferred from the target to the substrate. The SWN sustain no observable damage during the deposition process. Using SWN in combination with polymers as the target material, SWN/polystyrene and SWN/polyethylene glycol composite films were made. These films can be deposited on a variety of substrates, e.g., Si, glass, plastic, and metal, using the same target and deposition conditions. SEM micrographs show that the SWN were uniformly distributed in the film. Using a simple contact mask, SWN composite films 20 um diameter patterns can be produced.
