Abstract Carbon nanotube (CNT) films are gaining traction in applications such as transparent conductive films, electro-magnetic shields and thin film heaters. However, to date, few cost-effective large-area CNT coating methods have been reported. Here, we present a roll-to-roll (R2R) slot-die coating process for thin film CNT heaters. In this process, a CNT suspension is continuously coated on a PET film substrate and subsequently dried and packaged. This process allows for continuous square-meter-size CNT coating. The electrical resistance and thermal map of these samples are measured by high definition infrared (IR) thermography. Anti−/de-icing demonstrations of R2R CNT coated samples are performed inside a cold room and outdoor atmospheric icing conditions. The successful R2R coating of CNTs and anti−/de-icing demonstrations show promise for application of CNTs in large area applications, such as the de-icing of ships, for which strict regulations are put in place for vessels operating in polar waters.

用于电热加热的碳纳米管薄膜的卷对卷涂层

摘要 碳纳米管 (CNT) 薄膜在透明导电薄膜、电磁屏蔽和薄膜加热器等应用中越来越受欢迎。然而，迄今为止，几乎没有报道过具有成本效益的大面积碳纳米管涂层方法。在这里，我们提出了一种用于薄膜 CNT 加热器的卷对卷 (R2R) 槽模涂布工艺。在此过程中，CNT 悬浮液连续涂覆在 PET 薄膜基材上，随后干燥和包装。该过程允许连续平方米大小的 CNT 涂层。这些样品的电阻和热图是通过高清晰度红外 (IR) 热成像来测量的。R2R CNT 涂层样品的防/除冰演示在冷室和室外大气结冰条件下进行。
