3D-printing is an emerging technology that can be used for the fast prototyping and decentralised production of objects with complex geometries. Concretely, carbon-based 3D-printed electrodes have emerged as promising components for electrochemical capacitors. However, such electrodes usually require some post-treatments to be electrically active. Herein, 3D-printed nanocomposite electrodes made from a polylactic acid/nanocarbon filament have been characterised through different carbonisation temperatures in order to improve the conductivity of the electrodes via insulating polymer removal. Importantly, the carbonisation temperature has demonstrated to be a key parameter to tailor the capacitive behaviour of the resulting electrodes. Accordingly, this work opens new insights in advanced 3D-printed carbon-based electrodes employing thermal activation.
3D打印是一种新兴技术，可用于快速制造具有复杂几何形状的物体原型并进行分散式生产。具体而言，基于碳的3D打印电极已成为电化学电容器的有前景的组件。然而，此类电极通常需要一些后处理才能具有电活性。在此，由聚乳酸/纳米碳长丝制成的3D打印纳米复合电极已通过不同的碳化温度进行了表征，以便通过去除绝缘聚合物来提高电极的导电性。重要的是，碳化温度已被证明是调整所得电极电容行为的关键参数。因此，这项工作为采用热活化的先进3D打印碳基电极开辟了新的见解。
