Cross-sectional description of core-shell rod fabrication procedure. (a–b) Au/Pd is sputtered onto the PCTE membrane and serves as the working electrode for Ni electrodeposition. The inset in (b) is an SEM image of a 3 μm Ni tube after deposition. (c) PCTE membrane is immersed in uncured PDMS and set inside a PDMS well structure. (d) The sample is thermally cured, and the upper layer of PDMS and Au/Pd is removed to expose the PCTE membrane. (e) The PCTE membrane is dissolved with DCM, and rods are rinsed with ethanol. The appropriate fluid is added, and the sample is sealed.
