将碳纳米纤维（CNFs）和石墨薄片微粒添加到热塑性聚苯乙烯聚合物中，旨在制造适用于3D打印的新型导电混合物。评价各种聚合物/碳共混物作为可印刷电活性材料的适用性。开发了导电聚苯乙烯复合材料，并将其与市售聚苯乙烯（HIPS）一起用于制造适用于电化学实验的电极。制备并评价了电极用于1，1'-二茂铁二甲醇水溶液的循环伏安法和通过阳极溶出的Pb2+水溶液的差分脉冲伏安法检测。聚苯乙烯/CNF/石墨（80/10/10wt%）复合材料提供了良好的导电性和具有明确限定的活性几何表面积的稳定的电化学界面。印刷电极与聚苯乙烯壳形成稳定的界面，对背景伏安响应给出良好的信号，并且在抛光后可重复使用。
Carbon nanofibres (CNFs) and graphite flake microparticles were added to thermoplastic polystyrene polymer with the aim of making new conductive blends suitable for 3D-printing. Various polymer/carbon blends were evaluated for suitability as printable, electroactive material. An electrically conducting polystyrene composite was developed and used with commercially available polystyrene (HIPS) to manufacture electrodes suitable for electrochemical experiments. Electrodes were produced and evaluated for cyclic voltammetry of aqueous 1,1'-ferrocenedimethanol and differential pulse voltammetry detection of aqueous Pb2+ via anodic stripping. A polystyrene/CNF/graphite (80/10/10wt%) composite provides good conductivity and a stable electrochemical interface with well-defined active geometric surface area. The printed electrodes form a stable interface to the polystyrene shell, give good signal to background voltammetric responses, and are reusable after polishing.
