In this work, the plating of high‐quality amorphous nickel–phosphorous coating with low resistivity of 0.45 µΩ m (298 K) on complex 3D printed polymeric structures with high uniformity is reported. Such a polymer metallization results in an effective conductivity of 4.7 × 104 S m−1. This process also allows flexible structures to maintain their flexibility along with the conductivity. Octet‐truss structures with nickel–iron‐(oxo) hydroxide nanosheets electrodeposited onto further displays excellent water‐splitting performance as catalytic electrodes, i.e., in KOH (1 m, aq), a low oxygen evolution reaction (OER) overpotential of 197 mV at 10 mA cm−2 and Tafel slope of 51 mV dec−1. Using this light‐weight electrode with high specific area, strength, and corrosion resistance properties, a fully functional water‐splitting system is designed and fabricated through the concentric integration of 3D printed components. A dense polymeric mesh implemented is also demonstrated as an effective separator of hydrogen and oxygen bubbles in this system.

3D 打印聚合物的金属化及其作为全功能水分解系统的应用
在这项工作中，报道了在具有高均匀性的复杂 3D 打印聚合物结构上电镀了低电阻率 0.45 µΩ m (298 K) 的高质量非晶镍磷涂层。这种聚合物金属化导致4.7×10 4 S m -1的有效电导率。该过程还允许柔性结构保持其灵活性和导电性。电沉积有镍-铁-(氧)氢氧化物纳米片的八角桁架结构进一步显示出作为催化电极的优异的水分解性能，即在 KOH ( 1 m ，aq) 中，析氧反应 (OER) 过电势为 197 mV在10 mA cm -2和塔菲尔斜率51 mV dec -1下。利用这种具有高比面积、高强度和耐腐蚀性能的轻质电极，通过 3D 打印组件的同心集成设计和制造了功能齐全的水分解系统。实施的致密聚合物网也被证明是该系统中氢气和氧气气泡的有效分离器。
