Abstract

Vanadium dioxide (VO2) is a promising smart window coating due to its thermochromic ability. However, its practical application is still on hold due to some limitations. For instance, a thin film coating of VO2 suffers from low visible transmittance (Tvis). A new and simple technique to solve this restriction is by embedding nanoparticles onto film. Hence, this paper presents a preparation of nanocomposite coating derived from hydrothermally synthesized VO2 with improved Tvis. Using polyvinylpyrrolidone (PVP) as host matrix, nanostructured VO2 is dispersed onto a glass sample via a spin coating process. X-ray diffraction (XRD) scan showed the presence of monoclinic VO2 in the film. Surface analysis of the sample was carried out using atomic force microscopy (AFM). Based on the results, the roughness of the scanned area (1.5x1.5 μm2) has a mean height (Sa), and root mean square height (Sq) of 3.94 nm and 2.73 nm, respectively. Finally, calculation of the optical properties of the sample was done with the aid of a UV-vis spectrophotometer. Accordingly, the prepared nanocomposite film has a Tvis of 79.81% which is significantly higher than a thin film sample (Tvis = 65%).
