Figure 2From: Well-integrated ZnO nanorod arrays on conductive textiles by electrochemical synthesis and their physical propertiesFE-SEM micrographs. Integrated ZnO NRAs on the seed-coated CT substrate at an external cathodic voltage of −2 V for 1 h under ultrasonic agitation. (a) Low magnification, (b) medium magnification, and (c) high magnification. The insets of (c) show the magnified FE-SEM image of the selected region and the photographs of the bare CT and the ZnO NRAs integrated CT substrate.Back to article page
