SEM images of the CNT/PVA/ZnO composite with m(CNT):m(PVA) of 0.5 and wzn2+ of 2 × 10−5 mol/L: (a) overall array appearance of the CNT/PVA/ZnO, (b) overall morphology of the CNT/PVA film with inset of magnified morphology of the CNTs (×5.0k), (c) overall morphology of the CNT/PVA film with CNT clumps (×3k), (d) overall morphology of the nano-ZnO array (×2.0k), (e) high-magnification image of the morphology of the large-sized nano-ZnO with disorganized crystals (×43k), and (f) high-magnification image of the morphology of the small-sized nano-ZnO array with a vertical crystal arrangement (×33k).
