Effect of modified ITO substrate on electrochromic properties of polyaniline films

Cerium dioxide/polyaniline core–shell nanocomposites

“…Conducting polymers are finding numerous applications in various electronic devices such as electromagnetic interference shielding [1], rechargeable battery [2], display [3], electrochromic device [4] and chemical sensor [5]. Among the conducting polymers, polyaniline (PANI) is used frequently because of its environmental stability, high processability and intrinsic redox reaction, and its electrical behavior can be reversibly controlled by charge-transfer doping or protonation [6].…”

Disposable electrochromic polyaniline sensor based on a redox response using a conventional camera: A first approach to handheld analysis

“…To prepare the electrochromic sensor, a polymeric film of PANI sensing material is deposited on an ITO electrode by cyclic voltammetry from a solution containing 0.2 M aniline and 0.5 M H 2 SO 4 working between -0.2 and 1.1 V (0.05 V × s -1 ) [33,34]. The layer thickness of PANI is related to the cycle number used.…”

“…Figure 3 shows the two regions: first bottom layer: PANI polymer; second upper layer: ITO bare electrode. The PANI film appears using AFM as a rough inhomogeneous layer [34] with an average thickness of all surface of (0.46 ± 0.05) µm, which indicates a volume of PANI on ITO of 1.012 × 10 -4 cm 3 . This decrease in the electrochromic response is due to deprotonation of the aniline rings at high pH values [33].…”

Molybdate hexacyanoferrate (MoOHCF) thin film: A brownish red Prussian blue analog for electrochromic window application

“…Organic polymers, e.g. polyaniline (PANI) [11,12], polypyrrole (PPy) [13], poly (3,4-ethylenedioxythiophenes) (PEDOT) [14,15], have advantages of multi-color electrochromism, fast response, high coloration efficiency and easy process, but the band-shift characteristics and susceptibility to UV render them more suitable for display rather than window application. The most famous electrochromic metal oxide is WO 3 [16][17][18].…”
