报道了一种国产炭黑/聚乳酸复合长丝的研制。优化的长丝含有28.5%wt.通过熔融沉积成型（FDM）技术，获得了300 μ m的炭黑，并将其用于改进型电化学传感器的3D打印。利用所制备的灯丝构建了一个简单的电化学体系，并将其用于检测水样中的邻苯二酚和对苯二酚以及牛奶中的过氧化氢。邻苯二酚和对苯二酚的测定成功地进行了差分脉冲伏安法，呈现LOD值分别为0.02和0.22 µmol L−1，自来水中的回收率值范围为91.1%至112%。此外，用普鲁士蓝修饰CB-PLA电极可以在0.0 V（相对于炭黑参比电极）下对牛奶样品中的过氧化氢进行非酶安培检测，线性范围为5.0至350.0 mol L−1，检测限较低（1.03 µmol L−1）。因此，CB-PLA可以成功地用作增材制造的电化学传感器，并且简单的长丝制造工艺允许其在多种应用中进行探索。在线版本包含补充材料，可通过10.1007/s 00604 -022-05511-2获得。
The development of a homemade carbon black composite filament with polylactic acid (CB-PLA) is reported. Optimized filaments containing 28.5% wt. of carbon black were obtained and employed in the 3D printing of improved electrochemical sensors by fused deposition modeling (FDM) technique. The fabricated filaments were used to construct a simple electrochemical system, which was explored for detecting catechol and hydroquinone in water samples and detecting hydrogen peroxide in milk. The determination of catechol and hydroquinone was successfully performed by differential pulse voltammetry, presenting LOD values of 0.02 and 0.22 µmol L−1, respectively, and recovery values ranging from 91.1 to 112% in tap water. Furthermore, the modification of CB-PLA electrodes with Prussian blue allowed the non-enzymatic amperometric detection of hydrogen peroxide at 0.0 V (vs. carbon black reference electrode) in milk samples, with a linear range between 5.0 and 350.0 mol L−1 and low limit of detection (1.03 µmol L−1). Thus, CB-PLA can be successfully applied as additively manufactured electrochemical sensors, and the easy filament manufacturing process allows for its exploration in a diversity of applications. The online version contains supplementary material available at 10.1007/s00604-022-05511-2.
