Fabricated SMNWs with different ZnO NPs concentrations. (a) Low-resolution SEM image of 5-μ m-long SMNW, entrapped ZnO NPs with uniform structure. (b) Highly magnified image of 5 wt.% ZnO NP-entrapped PANI nanowire with 97 nm height and 133 nm width. Diameters of the observed particles are 33.90 and 35.39 nm. (c) 10 wt.% ZnO NP-entrapped PANI nanowire with 108 nm height and 110 nm width. Diameters of the observed particles are 54.87 and 59.42 nm. (d) 20 wt.% ZnO NP-entrapped PANI nanowire with 98 nm height and 80 to 110 nm width. It can be seen that the agglomerated particles greatly changes surface morphology of the SMNW with taped shape.
