Abstract:Hydrophobic materials made of silica as a coating for glasses are very attractive. The synthesis of silica (SiO2) from rice husk ash was successfully carried out using the sol-gel method. The hydrophobic silica composition is made with four variations of silica, consisting of 0.5, 1.0, 1.5, 2.0 g and polydimethylsiloxane (PDMS) keep constant in 20 g. The raw material was first characterized by X-ray Fluorescence (XRF) to investigate element composition. Then, silica powder obtained from rice husk ash was chara… Show more
