Preparation and characterization of polyindole-ZnO composite polymer electrolyte with LiClO4

This paper describes the preparation and conductivity studies of polyindole-ZnO composite polymer electrolyte (CPE) with LiClO4 Polyindole-ZnO-based polymer nanocomposites were prepared by chemical method and characterized by XRD, infrared (IR), scanning electron microscope (SEM), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA) The IR spectrum confirms the intermolecular interaction between polyindole and ZnO The significant spectral changes of polyindole and ZnO nancomposites reveal the strong interaction between polyindole and ZnO nanoparticles The structural morphologies of the ZnO, polyindole, and polyindole-ZnO are obtained from SEM The TEM image of polyindole nanocomposite shows that ZnO is embedded in polyindole matrix An enhanced conductivity of 4 405 x 10(-7) Scm(-1) at 50 degrees C for the CPE was determined from impedance studies
