Optical and Electrical Studies of Polyaniline/ZnO Nanocomposite
Polyaniline (Pani)/ZnO nanocomposite with diameter 40–50 nm was successfully fabricated by coprecipitation method of ZnO via in situ polymerization of Pani. X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), fourier transformation infrared (FT-IR), UV-Vis absorption s...
