Novel ultra-thin PANI nanorods were growth on the aspheric-shape C-ZIF-8 seed layer coated stainless steel wire mesh (SSWM) flexible substrate as an elastic electrode for the flexible capacitor. Synthesized by Unipolar Pulse Electrodeposition (UPED) method, the unique ultra-thin thickness of C-ZIF/PANI nanorods electrode (10 - 20 µm) were capable of withstanding under critical flexes situation, due to losing the flexion strength as convergence or divergence between the aspheric-shape C-ZIF-8 particles. The morphology growth of PANI nanorods was significantly dependent on the anilinium micellar transformation, relatively long relaxation period (off-time), and the electrodeposit time and cycles numbers. UPED electrodeposition strategy preform to control the electrodeposition cycles and time. BET surface measurement, scanning electron microscopy SEM, X-ray diffraction, and FTIR spectra were measured to characterize the surface morphology of the elastic electrode. Besides, the phenomena role of UPED method in the fabrication process were discussed.
