Figure 3From: Well-integrated ZnO nanorod arrays on conductive textiles by electrochemical synthesis and their physical propertiesFE-SEM micrographs. ZnO NRAs grown on (a), the bare CT substrate with the ultrasonic agitation; and (b), the seed-coated CT substrate without the ultrasonic agitation. For comparison, the external cathodic voltage and growth time were −2 V and 1 h, respectively, as the same condition of Figure 2.Back to article page
