Carbon Nanotubes-Assisted Fabrication of TiO2 Nanocomposite Film for Optimum Electrochromic Application

Article Preview

Abstract:

Electrochromic composite film consisting of TiO2, chitosan (CS) and carbon nanotubes (CNTs) were fabricated on quartz and FTO substrates by the layer-by-layer self-assembly method (LbL). The multilayer film was characterized by UV-vis spectrum, scanning electron microscopy (SEM), cyclic voltammetry (CV) and chronoamperometric (CA) and in situ spectral electrochemicalmeasurements. The composite material shows high electrochromic performance, with the optical contrast of 11.5% and coloration efficiency of 21.7 cm2/C at 800 nm. The results indicate great promise for the TiO2-based film as a potential material in electrochromic devices.
