Three-dimensional (3D) hierarchical cabbage-like beta-cobalt hydroxide beta-Co(OH)(2)) nanostructures were fabricated onto conducive textiles composed of copper-coated polyethylene terephthalate fibers by a simple one-step electrochemical deposition (ED) method. Under an external applied voltage of -0.75 V for 4 h, the hierarchical cabbage-like beta-Co(OH)(2) nanostructures were well decorated on the conductive textiles. During the ED process, they were self-assembled by the tangled layers of nanoplate (thickness of similar to 45-55 nm) building blocks and exhibited a cabbage-shaped architecture. The structure and morphology of the as-prepared hierarchical cabbage-like beta-Co(OH)(2) nanostructures were characterized. The growth mechanism of cabbage like beta-Co(OH)(2) nanostructures was also investigated by varying the growth time. Moreover, the feasibility test for supercapacitors by measuring the electrochemical properties of the as-prepared nanostructures was performed by cyclic voltammetry and galvanic charge-discharge measurements. The obtained results show that the cabbage-like beta-Co(OH)(2) nanostructures on the conductive textile substrate exhibited superior energy storage performance compared to the nanoplate morphology.
