Both WOx <strong>and</strong> TiO 2 are very good electrochromic materials due to their strong electronphonon<br />

interaction capability. Thus, the combination <strong>of</strong> these two materials could possibly<br />

enhance the electrochromic performance. In our work, WOx was uniformly coated on TiO 2<br />

nanotubes using electrodeposition method from the solution <strong>of</strong> 0.5M Na 2 WO 4. . SEM <strong>and</strong><br />

EDX characterisation techniques were used to determine the surface morphology <strong>and</strong> film<br />

composition respectively. Electrochromic measurement was also conducted <strong>and</strong> the device<br />

performance was evaluated based on optical power reflective density. It was also compared<br />

with the performance <strong>of</strong> conventional RF sputter WO3 thin film coated on FTO glass.<br />
