Tailoring TiO2 Films: The Path to Superior Electrochromic Performance

The present study systematically explores the impact of variations in heating temperature and pH levels on the electrochromic features of electrodeposited TiO2 thin films. Notably, a TiO2 film prepared in an acidic medium and annealed at 450°C demonstrated exceptional EC properties. It exhibited a high transmission modulation of 17.18%, an impressive coloration efficiency of 58.8 cm2/C, and rapid switching kinetics. These results highlight the significance of optimizing synthesis conditions for TiO2 thin films to enhance their electrochromic performance. The findings of this research contribute valuable insights into tailoring the electrochromic behavior of TiO2, emphasizing the importance of pH and annealing temperature in achieving enhanced EC properties. The identified optimal conditions for TiO2 thin films open new avenues for the development of efficient and cost-effective electrochromic materials. This research advances the understanding of TiO2’s electrochromic capabilities and provides a promising candidate for diverse electrochromic applications, thereby expanding the potential impact of electrochromism in various technological fields.
