Abstract: There is an increasing trend in the application of hydrophobic nanocoating in the building industry mainly due to their favorable characteristics such as moisture behavior, self-cleaning and multi-functionality. The usage of such nanocoatings can be found on building surfaces such as walls, doors, windows and even roofs. Due to their positively perceived characteristics, such coatings are considered environmentally friendly, achieving self-sustainability and highly popular for green building usage. The aim of this paper is to investigate the effects of functionalized SiO2 spheres on hydrophobic nanocoatings. In this study, various different silanes and polymer(glues) are used to test their hydrophobicity by measuring their individual Water Contact Angle (WCA). As such, this study strives to uncover the most effective way of enhancing the hydrophobicity of nanocoating for its usage for green buildings. To research the effects of functionalized SiO2 spheres after integrating them onto hydrophobic coatings, through studying various silanes and polymer and testing their hydrophobicity and measurement of WCA, we aim to uncover the best method of enhancing hydrophobicity for its usage on green building. With due diligence on extensive research, results have shown that superhydrophobic coatings are coatings that are able to achieve a WCA of more than 150°. The WCA is of a surface is measured by drop-coating method and in-dept analysis of results has led to the discovery that the integration of SiO2 spheres can indeed enhance hydrophobicity.
