We report here a simple filtration method for the scalable fabrication of user-designed and carbon-nanomaterial-based electrode arrays using laser-cut poly(vinyl chloride) (PVC) tape templates. This method can produce electrode arrays with high uniformity and low resistance from the dilute dispersions of single-walled carbon nanotubes (SWNTs) and graphene nanoplatelets (GNPs). For these two carbon arrays, the SWNT array is demonstrated to possess several interesting properties, e.g., good mechanical properties, excellent flexibility, and favorable electrochemical behavior. Moreover, its porous structure enables the construction of a paperlike solid-state electrochemical sensor using Nafion electrolytes, which is suitable for the on-site monitoring of trace phenol pollutants in electrolyte-free water. Besides, an electrochemically addressable 36-zone sensor was constructed by this method. With the aid of an inexpensive 3D printer, the addressable sensor can achieve the semiautomatic and high-throughput evaluation of antioxidant capacity on a series of vegetables and fruits using a single-channel electrochemical analyzer.

激光切割聚合物胶带模板，用于用户设计的基于碳纳米材料的电化学传感器的可伸缩过滤制造

我们在这里报告了一种简单的过滤方法，用于使用激光切割的聚氯乙烯（PVC）胶带模板可扩展地制造用户设计的基于碳纳米材料的电极阵列。这种方法可以从单壁碳纳米管（SWNT）和石墨烯纳米片（GNP）的稀分散液中生产出具有高均匀性和低电阻的电极阵列。对于这两个碳阵列，SWNT阵列具有多种有趣的性能，例如良好的机械性能，出色的柔韧性和良好的电化学性能。此外，其多孔结构使得能够使用Nafion电解质构造纸状固态电化学传感器，该传感器适用于现场监测无电解质水中痕量的苯酚污染物。除了，通过这种方法构建了一个可电化学寻址的36区传感器。借助廉价的3D打印机，可寻址传感器可以使用单通道电化学分析仪实现对一系列蔬菜和水果的抗氧化能力的半自动和高通量评估。
