Abstract
Vanadium dioxide film, to be used as a thermochromic material for smart glazing, were prepared and fabricated on glass substrate via a polymer assisted deposition (PAD). Poly (vinyl pyrrolidone) (PVP) and poly (vinyl alcohol) (PVOH) were used as the film former to control the viscosity of precursor solution and interact with vanadium ions. The structural characteristic of vanadium oxides films was optimized in this work using Taguchi's experimental design. The optimization was performed by considering the effect of annealing temperature, annealing time and heating rates on film thickness and XRD patterns of the prepared film. The results from XRD patterns indicated that the optimum conditions corresponding to the formation of vanadium dioxide (VO2), regardless of the polymer type, is that by using the annealing time and temperature of 6 h and 450 °C, respectively.
