Polyaniline,ZnO and polyaniline/ZnO nanocomposite thin films are coated on glass substrates using the spray pyrolysis technique.The samples are characterized by the XRD,SEM,EDAX,UV-Vis and I-V characteristics. The XRD analyses confirm that the spray-coated polyaniline and ZnO thin films have orthorhombic and hexagonal structures,respectively,and optical bandgap energy decreases from 3.81 to 3.41 eV with the addition of a Zn atom.SEM analysis of the polyaniline/ZnO nanocomposite thin films shows that there is an agglomeration of ZnO particles with uniform distribution in the polyaniline matrix,and the diode characteristics of the polyaniline /ZnO nanocomposite show weak rectification behavior.Parameters such as the ideality factor,reverse saturation current and barrier height are calculated from the I-V characteristics.
Polyaniline, ZnO and polyaniline / ZnO nanocomposite thin films are coated on glass substrates using the spray pyrolysis technique. The samples are characterized by the XRD, SEM, EDAX, UV-Vis and IV characteristics. The XRD analyzes confirm that the spray-coated polyaniline and ZnO thin films have orthorhombic and hexagonal structures, respectively, and optical bandgap energy decreases from 3.81 to 3.41 eV with the addition of a Zn atom. SEM analysis of the polyaniline / ZnO nanocomposite thin films shows that there is an agglomeration of ZnO particles with uniform distribution in the polyaniline matrix, and the diode characteristics of the polyaniline / ZnO nanocomposite show weak rectification behavior. Parameters such as the ideality factor, reverse saturation current and barrier height are calculated from the IV characteristics.
