提出了多壁碳纳米管（MWCNT）和炭黑（CB）的组合以生产高性能导电的回收增材制造长丝。通过TGA、XPS、拉曼和SEM表征了细丝和随后增材制造的电极，并显示出优异的低温柔性。与仅使用CB的相同内部生产的定制长丝相比，MWCNT/CB长丝表现出改善的电化学性能。得到的非均相电化学速率常数为1.71（± 0.19）× 10−3 cm s−1，比常用的商用导电CB/PLA提高了近6倍。该灯丝成功地用于对乙酰氨基酚和苯丙酮的同时测定，线性范围分别为5-60和5-200 μM，灵敏度分别为0.05 μA μM−1和0.14 μA μM−1，检测限分别为0.04 μM和0.38 μM。呈现了一种在家打印设备，其中由rPLA组成的可移动盖子可以放置在饮用容器上，并且工作，计数器和参考组件由我们定制的MWCNT/CB长丝制成。在家打印的设备被成功地用于确定这两种化合物的真实的药品，在三个真实的样品的范围内的回收率在87%和120%之间。这项工作为使用具有不同形态和物理化学性质的碳材料的组合制造新的高导电细丝及其应用铺平了道路，以生产具有极大改善的电化学性能的增材制造电极。在线版本包含补充材料，可通过10.1007/s 00604 -023-06175-2获得。
The combination of multi-walled carbon nanotubes (MWCNT) and carbon black (CB) is presented to produce a high-performance electrically conductive recycled additive manufacturing filament. The filament and subsequent additively manufactured electrodes were characterised by TGA, XPS, Raman, and SEM and showed excellent low-temperature flexibility. The MWCNT/CB filament exhibited an improved electrochemical performance compared to an identical in-house produced bespoke filament using only CB. A heterogeneous electrochemical rate constant, of 1.71 (± 0.19) × 10−3 cm s−1 was obtained, showing an almost six times improvement over the commonly used commercial conductive CB/PLA. The filament was successfully tested for the simultaneous determination of acetaminophen and phenylephrine, producing linear ranges of 5–60 and 5–200 μM, sensitivities of 0.05 μA μM−1 and 0.14 μA μM−1, and limits of detection of 0.04 μM and 0.38 μM, respectively. A print-at-home device is presented where a removable lid comprised of rPLA can be placed onto a drinking vessel and the working, counter, and reference components made from our bespoke MWCNT/CB filament. The print-at-home device was successfully used to determine both compounds within real pharmaceutical products, with recoveries between 87 and 120% over a range of three real samples. This work paves the way for fabricating new highly conductive filaments using a combination of carbon materials with different morphologies and physicochemical properties and their application to produce additively manufactured electrodes with greatly improved electrochemical performance.
