| Abstract | Fogging, which is condensation of water in the form of small droplets on a surface, typically reduces visibility causing various problems. Here, we developed a nanostructured thin film that acts as an antifogging surface to prevent the condensation of water. The said antifogging thin film is composed of nanoparticulate tin dioxide (SnO2) and has superhydrophilic nature. Spark deposition technique is used to deposit the SnO2 thin film on glass substrates. Scanning electron microscopy revealed the sizes of individual nanoparticles less than 100 nm. The deposited thin films showed good transparency in the visible light region and exhibited water contact angle less than 5° indicating their superhydrophilic nature. Water condensation experiments on these superhydrophilic coatings showed very less condensation compared to bare glass substrates. The condensation of water, or in other words the antifogging property of the superhydrophilic thin films was found to be affected by the amount of oxide material deposited per unit area of the substrate. Results from this study indicate potential use of superhydrophilic oxide thin films as antifogging coatings, which has the benefit of high chemical and thermal stability. |
