Abstract

Abstract Nanostructured indium tin oxide (ITO) thin films have been grown by chemical spray pyrolysis method on flexible polyimide (PI) polymeric substrates at various temperatures (400, 450 and 500 °C) using solutions of indium and tin chlorides as precursors. The composition, microstructure, surface morphology, thermal, electrical, and optical characteristics have been analysed by FT-IR, UV–Vis, X-ray diffraction, SEM, EDAX, atomic force microscopy, electrical measurements, TGA, etc. X-ray diffraction measurements employing Cu-K α radiation showed that the ITO films were polycrystalline with a cubic bixbyite structure. An increment in average grain size, electrical conductivity and optical transmittance was observed at higher substrate temperature. ITO-coated films maintained the mechanical properties and stability of the pristine PI films. The adhesion between surface ITO layers and PI matrix was found acceptable. Graphical Abstract
