ABSTRACT

Electrophoretic deposition (EPD) is a powerful technique to assemble carbon nanotube (CNT) coatings and composite films with controlled architectures. This comprehensive review of the EPD of CNTs and CNT-containing composites focuses on achievements within the last 15 years and ongoing challenges. Stable CNT suspensions are a pre-requisite for successful EPD and have been prepared by a variety of strategies, discussed here. The resulting film microstructure is determined by the initial feedstock, the suspension, and the EPD approach applied, as well as a variety of EPD processing parameters. Nanocomposites can be prepared via co-deposition, sequential deposition, or post-deposition treatments, to introduce metallic, ceramic or polymeric phases. There are numerous potential applications for both homogeneous and patterned CNT films, including as structural reinforcements for composites, as field emission, energy storage and conversion devices, as well as in biomedical applications. The advantages and disadvantages of EPD processing in these contexts are discussed.

摘要

电泳沉积 (EPD) 是一种强大的技术，用于组装具有受控结构的碳纳米管 (CNT) 涂层和复合膜。对碳纳米管和含碳纳米管复合材料的 EPD 的全面审查侧重于过去 15 年的成就和持续的挑战。稳定的 CNT 悬浮液是成功 EPD 的先决条件，并已通过各种策略制备，此处讨论。最终的薄膜微观结构由初始原料、悬浮液和应用的 EPD 方法以及各种 EPD 加工参数决定。纳米复合材料可以通过共沉积、顺序沉积或沉积后处理来制备，以引入金属、陶瓷或聚合物相。均质和图案化的 CNT 薄膜有许多潜在的应用，包括作为复合材料的结构增强材料、场发射、能量存储和转换设备以及生物医学应用。讨论了在这些情况下 EPD 处理的优点和缺点。
