Abstract

This research work presents the design of a mixture of SiO₂/TiO₂ that increases the surface roughness and hydrophobicity of methyltrimethoxysilane (MTMS) coated glass. The deposition of SiO₂, TiO₂, and MTMS were conducted using a layer by layer dip coating technique. The SiO₂/TiO₂ coating was derived from complete hydrolysis of tetraethylorthsilicate and titanium tetraisopropoxide. In order to evaluate and compare the performance of SiO₂/TiO₂/MTMS coated glass, the SiO₂/SiO₂/MTMS and TiO₂/TiO₂/MTMS were also fabricated. SiO₂/TiO₂/MTMS samples displayed the highest water contact angle. The topography of surfaces showed that SiO₂/TiO₂/MTMS exposed higher surface roughness with micro-nanoscale structures. The sequence of SiO₂ and TiO₂ influenced the water contact angle and the stability of the coatings. SiO₂/TiO₂/MTMS produced higher contact angle and stability than TiO₂/SiO₂/MTMS.
