Fabrication of solid contact reference electrodes (SCREs) by three-dimensional (3D) printing using a PVC-based composite is described. PVC highly loaded with KCl forms the electroactive part of the electrode and is deposited on an ABS 3D printed base equipped with an electric contact made of Ag/AgCl. The reference electrode is characterized by very good potential stability in potentiometric tests as well as excellent performance in acid–base titration.

通过3D打印制造的具有PVC基复合电活性元件的固体接触参比电极

描述了通过使用基于PVC的复合材料的三维（3D）印刷来制造固体接触参考电极（SCRE）。富含KCl的PVC形成电极的电活性部分，并沉积在配备有由Ag / AgCl制成的电触点的ABS 3D打印基底上。参比电极的特点是在电位测试中具有非常好的电势稳定性，并且在酸碱滴定中具有出色的性能。
