Abstract: Nowadays, the use of nanocoating is pervasive in the in the industry due to their multifunctionality. Hydrophobic nanocoating are gaining a lot of popularity due to the increasing number of smart green home applications. Hydrophobicity is the key factor for ‘self-cleaning’ coatings which have the great potential to be applied on the buildings, vehicles and even food products. Therefore, reducing the use of energy, labour and cost for the maintainability. The aim of this paper is to investigate the effect of functionalised SiO2 spheres on hydrophobic nanocoatings on different surface substrates. In this study, different silanes and polymers(glues) are tested for their hydrophobicity on glass and kitchen tiles by measuring the WCA. By varying factors such as the thickness of the coatings, addition of functionalised SiO2 spheres and testing in different containers, the study hopes to uncover an effective way of enhancing the hydrophobicity of nanocoating on glass and tiles. After extensive research and experiments, we discovered coatings that are almost superhydrophobic which able to achieve WCA above 120 and very hydrophilic coatings that has WCA less than 10. The fabrication can be carried out by a simple drop-coating technique and can be cured under room temperature. After a thorough analysis of the results, we found out that the addition of functionalised SiO2 spheres can greatly affect the hydrophocbity. With the comprehensive results obtained, this study serves to be a benchmark for the investigation of nanocoatings on tiles and glass slides. Keywords: Hydrophobic, nanocoatings, silane, SiO2 spheres
