Abstract

The purpose of this research was to study the effect of silica addition on TEOS-OTES hybrid films on hydrophobic properties. The film was prepared by sol-gel method from solvents such as, tetraethylorthosilicate (TEOS), octyltriethoxysilane (OTES), isopropanol alcohol (IPA), deionized water (DI) and silica particles. The sols were prepared at a volumetric ratio of TEOS : OTES : IPA: Dl equal to 2.4: 0.6:94: 3. Silica particles at 0.5, 1, 3, 5 and 10 weight percent were subsequently added to the sol. The sol-gel precursor was spin-coated onto glass slides and heated at 200-450 °C for 30 minutes. After the heat treatment, the film properties were characterized by FT-IR, UVVIS Spectroscopy, XRD, AFM and contact angle. It was found that contact angle of film increased with increasing amounts of silica particles whereas the transmittance decreased with increasing amounts of silica particles. The optimal hydrophobic (Water contact angle of 119gif.latex?\pm4.1°) and optical (transmittance of 75%) properties were obtained in TEOS-OTES hybrid film containing 1 weight percentage of silica particles.
