增材制造（也称为 3D 打印）正在电化学领域中得到应用，以可重复地开发具有导电特性的复杂几何形状。在这项研究中，我们探讨了 3D 打印丙烯腈丁二烯苯乙烯 (ABS)/炭黑电极的电化学行为是否受到打印方向的影响。电极在水平和垂直方向上印刷。水平方向产生光滑表面（HPSS 电极）和相对较粗糙的表面（HPRS 电极）表面。使用循环伏安法、电化学阻抗谱和计时电流法对电极进行表征。对于各种氧化还原电对，与水平印刷方向生成的两个电极表面相比，垂直印刷（VP）电极显示出增强的电流响应。没有观察到电容响应的差异，这表明所有类型的电极的导电表面积是相同的。与 HPSS 和 HPRS 电极相比，VP 电极具有降低的电荷转移电阻和未补偿溶液电阻。总体而言，垂直方向印刷的电极可增强电化学性能，我们的研究表明印刷方向是可用于增强传感器性能的关键因素。
Additive manufacturing also known as 3D printing is being utilised in electrochemistry to reproducibly develop complex geometries with conductive properties. In this study, we explored if the electrochemical behavior of 3D printed acrylonitrile butadiene styrene (ABS)/carbon black electrodes was influenced by printing direction. The electrodes were printed in both horizontal and vertical directions. The horizsontal direction resulted in a smooth surface (HPSS electrode) and a comparatively rougher surface (HPRS electrode) surface. Electrodes were characterized using cyclic voltammetry, electrochemical impedance spectroscopy and chronoamperometry. For various redox couples, the vertical printed (VP) electrode showed enhanced current response when compared the two electrode surfaces generated by horizontal print direction. No differences in the capacitive response was observed, indicating that the conductive surface area of all types of electrodes were identical. The VP electrode had reduced charge transfer resistance and uncompensated solution resistance when compared to the HPSS and HPRS electrodes. Overall, electrodes printed in a vertical direction provide enhanced electrochemical performance and our study indicates that print orientation is a key factor that can be used to enhance sensor performance.
